Final answer:
To better distribute heat during microwave cooking, use a lower power setting and stir food regularly. Do not place food in a metal container, as it is unsafe.
Step-by-step explanation:
During microwave cooking, to ensure heat is better distributed, one should use a lower power setting to give food more time to evenly absorb the energy (a). Stirring the food regularly (b) is also recommended to redistribute the heat throughout the food. Placing food in a metal container is not a safe practice for microwave use, as metal can spark and cause fires (c). Moreover, cooking for shorter durations may not necessarily result in better heat distribution; rather, it could result in undercooking (d).
