Where applicant neither necessary nor proper party in suit of specific performance whether his presence is necessary for effective adjudication?

Specific Performance: This is when someone asks the court to force another person to fulfill a contract (usually to buy or sell property).
Necessary Party: A person who must be included in a lawsuit because the court cannot make a proper decision without them. If they are missing, the case can't move forward.
Proper Party: A person who should be included in a lawsuit because their involvement could help the court make a better decision, but the case can still proceed without them.
Applicant: The person applying to be part of the lawsuit.

The question tells us the applicant is neither necessary nor proper. This means their presence isn't crucial for a fair and complete decision. Therefore, they don't need to be part of the suit.

Therefore, the correct answer is B: No
