Thermodynamics tutorial Original made-up question 2-132 not found in textbooks

A hydroelectric power plant draws water at a flow rate of 71 cubic meters per second from a reservoir located 66 meters above the turbine. The turbine-generator system operates with an efficiency of 86 percent, and frictional losses in the piping are negligible. What is the expected electrical power output of the plant?
(a) 3.9 MW
(b) 39.5 MW
(c) 45 MW
(d) 53 MW
(e) 65 MW

This is a similar question to Electric power is to be generated in a hydroelectric
power plant that receives water at a rate of 70 m3/s from an elevation of 65 m using a turbine–generator with an efficiency of 85 percent. When frictional losses in piping are disregarded, the electric power output of this plant is (a) 3.9 MW (b) 38 MW (c) 45 MW (d) 53 MW (e) 65 MW
However the content in the video fully original, The question is not the same, the working and explanation is solved in my own way
