select the best answer for the question.

1. when all parts of a circuit are composed of conducting materials, the circuit is said to be

a. parallel.
b. shorted.
c. open.
d. closed.

mark for review (will be highlighted on the review page)

Explanation:

To solve this, we analyze each option:

• Option A: A parallel circuit refers to the arrangement of components (multiple paths for current), not about all parts being conducting. So A is incorrect.
• Option B: A shorted circuit is when there's an unintended low - resistance path, often bypassing a component, not related to all parts being conducting. So B is incorrect.
• Option C: An open circuit has a break in the conducting path, meaning not all parts are conducting. So C is incorrect.
• Option D: A closed circuit is one where the electrical path is complete, and this requires all parts of the circuit to be made of conducting materials so that current can flow. So D is correct.

Answer:

D. closed.
