Correct answer

A. B

Step-by-step solution

BCl3{BCl}_{3}

A group 13 element ^ ' X ^ ' reacts with chlorine gas to produce a compound XCl _ 3 . XCl _ 3 is electron deficient and

Boron react with chlorine gas to produce compound BCl3{BCl}_{3} which is electron deficient. It does not dimerize because of small boron atom. It react with ammonia to form aduct. In it ammonia act as lewis base and BCl3{BCl}_{3} act as lewis acid.
