The question was asked by my school teacher while I was bunking the class.

I need to ask this question from Sharded Cluster Data Management in section Sharding Concepts, Mechanics and Sharded Cluster of MongoDB

Answer 1

Correct option is (a) sh.deadForDLock() waits for a specified distributed sharded cluster lock

To elaborate: sh.stopBalancer() disables the balancer and waits for any in progress balancing rounds to complete.
