As complement of the Copulative verb is Nominative case.

Change, is situating → is situated

Replace, are practicing very hard → is practicing very hard
Subject of the verb must agree in number with verb. Here

subject of the verb is Captain which is singular so it must take singular verb.

The error is in Option A: Supposing if.
The word "supposing" and "if" have the same meaning in this context.
Using them together is redundant (unnecessary repetition).
You should use either "supposing" or "if," but not both.
For example, you can say: "Supposing it rains, what shall we do?" or "If it rains, what shall we do?"
So, the correct option is A: Supposing if because it contains the error.

Change, are into is

When two or more than two subjects are joined by 'Either, or' 'Neither, nor', the verb agrees with the subject nearest to it.

In this sentence, the phrase "None of two girls" is incorrect. It should be "Neither of the two girls". "None" is used to refer to no one or not any, while "neither" is used to refer to not one nor the other of two people or things. Additionally, "neither" should be followed by "of" and the plural form "the two girls" is more appropriate in this context.
So, the correct structure should be:
Neither of the two girls who were present appeared to be inclined to listen to sane advice.

Change, of all animals → than any other animal

In a comparative degree THAN is used. Also, the term of comparison must exclude the things compared by use of OTHER.

Change, I and my colleague → My colleague and I.

Error in order of pronouns.

Order of Pronoun Second person(2) + third (3)+ first person(1) in normal sentences. RULE-231
You, he and I have finished the work. (Normal idea)
I, you and he are to blame. ( here Confession of guilt is expressed , it's a negative idea, hence order is 123).

The sentence is: "Even if / the teacher has completed the / course the students cannot pass / unless they study themself."

1. "Even if": This part is perfectly fine. It means 'although' or 'despite the fact that'.
2. "the teacher has completed the": This part is also correct. The verb 'has completed' is in the Present Perfect tense, which is suitable here.
3. "course the students cannot pass": This part is also grammatically correct. 'cannot pass' is a correct usage.
4. "unless they study themself": Let's focus on this part.
* The word 'themself' is the mistake here.
* When the subject of the sentence is 'they' (which is a plural pronoun, referring to 'students'), we need to use the correct reflexive pronoun.
* For a plural subject like 'they', the correct reflexive pronoun is 'themselves'.
* 'Themself' is an incorrect form in standard English. It should always be 'themselves' when referring to a plural group.

So, the correct sentence should be: "Even if the teacher has completed the course, the students cannot pass unless they study themselves."

Therefore, the error is in the part "unless they study themself".

The correct answer is Option D.
