Circumstances will oblige me to go.

Solution (By Examveda Team)

The given sentence, “Circumstances will oblige me to go.”, is in the Active Voice. Here, “circumstances” is the subject, “will oblige” is the verb, and “me” is the object.

To change it into the Passive Voice, the object “me” becomes the subject. The verb phrase “will oblige” changes to “will be obliged”.

Thus:
Active: Circumstances will oblige me to go.
Passive: I shall be obliged to go by the circumstances.

Why Option B is correct: The meaning and grammatical structure of the original sentence are correctly retained. “Me” becomes “I”, and “will oblige” changes to the passive construction “shall be obliged”.

Why the other options are incorrect:

Option A: Incorrect. It does not change the sentence into the passive voice; it merely rearranges the meaning.

Option C: Incorrect. “I should go” changes the meaning and does not form the passive voice of the given sentence.

Option D: Incorrect. The phrase “obliged by the circumstances to go” is awkward in this construction. The standard passive transformation is “I shall be obliged to go by the circumstances.”

Final Answer: Option B — I shall be obliged to go by the circumstances.
