Final answer:
The Andretti twins d) imitated race car drivers by using pan lids as steering wheels, which reflects their childhood fascination with Formula One racing.
Step-by-step explanation:
The word that best describes how the Andretti twins played with pan lids in the house is d) imitated.
To imitate means to copy or mimic someone or something. The Andretti twins were pretending to be race car drivers, using pan lids as steering wheels, which is a clear act of imitation.
They were emulating what they saw in movie clips of races, likely imagining themselves as Formula One drivers, which was the most popular sport in Italy at the time.
