Answer

Explanation:

Step1: Recall power - generation principle in hydro - power plants

Hydro - power plants generate electricity based on the potential energy of water. The potential energy of water is related to the mass of water (which depends on the amount of water) and the height of the water column (related to the height of the dam).

Step2: Analyze each option

  • Option A: Just the number of generators and height of the dam is not a complete explanation. Generators are for converting energy, and height alone is not sufficient without considering water flow.
  • Option B: The area of Lake Mead and number of generators are not the key factors for power generation. Area of the lake does not directly translate to power - generating capacity without considering water flow and height.
  • Option C: The amount of water released through the dam determines the mass of water flowing, and the dam's height determines the potential energy of the water. These two factors are crucial for calculating the potential energy available for power generation in a hydro - power plant like Hoover Dam.
  • Option D: The quantity of water flowing into Lake Mead from the Colorado River is not the direct factor for power generation at the dam. The power generation is more related to the water flowing out of the dam and its height.
