Step 1: Specific Relief Act.
Contracts are specifically enforced only when monetary compensation is inadequate, e.g., sale of unique goods, land, or rare items.
Step 2: Analysis of options.
- (A) If compensation is adequate, then specific performance is not allowed.
- (B) Determinable contracts (like employment-at-will) cannot be specifically enforced.
- (C) Continuous duties (like personal services) cannot be supervised, hence not enforceable.
Step 3: Conclusion.
Since all listed situations are excluded, the correct answer is (D).
