Tortious Interference with Contract: Mock Test Mayhem!

Abbas Alibhai (C) vs Dastan & Company (D) is a case on tortious interference with contract. Briefly, D intervened in an existing contract between A and C, leading to its termination. The court finds D liable for compensatory damages.

Next question: A and B have a verbal contract, where A agrees to sell his property to B for Rs 1Cr. C, without A's knowledge, threatens B that he'll take legal action for encroachment on his land if he purchases the property. This results in B backing out. Who owes what to whom?

I scored 5/10 for this question; my main blunder was not realizing that C's action, even if it led to B's exit, is not direct interference with A-B contract. I was thinking it was a case of inducing breach of contract.
