Answer:A
Each Engine has 4 fans, if single fan failure then remaining three fan units will help to cool down the system. But if 2 fans failed then system will shutdown in no time.

In a VS1 and VS2 – there are 4 fans per engine. If one fan fails, the other 3 will accommodate by adjusting their fan speeds. If 2 fans fail, engine will shut down after 3min.

Should two fans fail, the engine will automatically shut down to prevent damage from overheating (https://www.emc.com/collateral/hardware/white-papers/h7138-workload-resiliency-vplex-wp.pdf)
