The answer is A) The Main Idea is implied - Heating a cooking systems in spacesuits use too much electricity
Step-by-step explanation
The text says"Heating and cooling systems inside a suit can moderate temperatures, but electric power to operate these systems limits the length of time the suit can be used before recharging. One way to reduce dependency of a spacesuit heating/cooling systems is to use materials for suit construction that have desirable thermal properties" so the energy depending on the heating/cooling systems inside the suit make the project and the design of it more difficult
