Choose the connector that can correctly combine the two given sentences to form one complex sentence:

A. You can borrow the book.

B. You have to return it tomorrow.

Correct option is B

The correct connector to combine the two sentences is (b) provided.
Correct complex sentence: You can borrow the book provided you return it tomorrow.
Detailed Explanation (English): The connector “provided” means on the condition that. It is used to express a condition similar to “if.” Here, borrowing the book is conditional on returning it the next day.
Grammatical rule used: “Provided / Provided that” is a subordinating conjunction used to express a condition. It can replace “if” in formal English.
Explanation of the grammatical rule in Hindi: “Provided” या “Provided that” का प्रयोग शर्त (condition) बताने के लिए किया जाता है। इस वाक्य में पुस्तक उधार लेने की शर्त है कि उसे कल लौटाना होगा। इसलिए सही वाक्य है — You can borrow the book provided you return it tomorrow.
Example: You can go out provided you finish your homework first.
Meanings of other options: · As: because / while (क्योंकि / जब) · Since: because / from that time (क्योंकि / तब से) · Unless: except if / if not (जब तक नहीं / यदि नहीं)
