Answer :
Final answer:
Insulators do not allow electric charge to flow freely, while semiconductors have properties between conductors and insulators. The correct answer to the question is 'insulators.'
Explanation:
Insulators are materials that do not allow the internal charge to flow freely, thus cannot conduct electric current appreciably when exposed to an electric field.
Semiconductors are materials that have properties between conductors and insulators, allowing manipulation of electric current and are integral in modern electronics.
Based on the description provided, the correct answer to the question is (c) aislantes (insulators).
