Evaluate the given options

• Option A refers to coupling gap, which is not backlash.
• Option B is a non-standard, incorrect term.

• (A) the space between couplings
• (B) the opposite of frontlash
• (C) the distance between conveyor roll centers
• (D) the clearance between gear teeth (Correct answer)
