Explanation:

A.Where is my practice if they want to be able to carry heavy trays without dropping them.

Incorrect grammar and sentence topic is lost.

Incorrect use of capitalization and the it should be a "them".

C. If waiters aren’t too much of a hurry, you get a fin customers by being to abrupt.

Sentence is unclear.
