The portion of the brick cut across its width and having its length equal to that of a full brick, is known as

ANS:B - queen closer

QUEEN CLOSER. Queen closer is the correct answer, since here it is clearly mentioned that the length is equal to that of full brick. And cut across the width means parallel to length.
When a brick is cut along its length, making it two equal halves then it is called queen closer. Thus a queen closer is a broken brick portion whose width is half as wide as the original brick. This is also called as queen closer half.
