Step 1: Understanding the Question.
According to Section 20 of the Civil Procedure Code (CPC), a person can file a suit where the cause of action arises. Here, the cause of action could arise in either Ahmedabad, where the goods were delivered, or in Delhi, where B conducts business.
Step 2: Analysis of Options.
- (A) In Ahmedabad only: This is incorrect, as B is in Delhi, and the suit could also be filed there.
- (B) In Delhi only: This is incorrect, as A can file the suit in Ahmedabad too.
- (C) In either Ahmedabad or Delhi: This is the correct answer, as A can file the suit in either place based on where the cause of action arises.
- (D) Anywhere in India: This is incorrect, as the suit must be filed within the jurisdiction related to the cause of action.
Step 3: Conclusion.
Thus, the correct answer is (C) In either Ahmedabad or Delhi.
