Simultaneous tripping of the circuit breaker at both ends of a transmission line is achieved by

Carrier current over the power line provides simultaneous tripping of circuit breakers at both ends of the line in one to three cycles.
Thereby high-speed fault clearing is obtained, which improves the power system stability.
The auto-reclosing simultaneous reclosing signal is sent thereby simultaneous (1 to 3 cycles) reclosing of the circuit breaker is obtained.
For simultaneous faults, carrier-current protection provides easy discrimination.

As per answer key "pilot protection" is true but there is mistake the right answer is "none".

Which of the following are the advantages of Aerial Bunched Cables (ABC)?

A given solar cell has the following specifications: Isc = 4 A and Voc = 0.7 V. Consider that 20 identical cells with the above specifications are to be interconnected to create a PV module. What is the open-circuit voltage of the PV module if all the solar cells are connected in a series configuration?

For M no. of series configuration of solar cell,
Open circuit voltage of PV module= M*Voc
= 20*0.7
= 14 V
Short circuit current of PV module = M*Isc
= 20*4
= 80 A
