Answer 1

The Correct Option is B

Step 1: Understand the purpose of the drop warwick. 
A drop warwick is specifically designed to engage the wheels of a runaway tub and arrest its motion in forward direction on inclines. 
Step 2: Differentiate it from other safety devices.
(A) Monkey catch and (D) backstay are used in different safety contexts (often backward movement). 
(C) Stop-blocks are physical barriers but are not the designated safety devices for automatic forward runaway prevention like drop warwick is.
