Answer

Explanation:

Step1: Recall current - brightness relationship

In a circuit, for identical bulbs, more current means more brightness. Also, current flows from the positive terminal of the battery to the negative terminal.

Step2: Analyze first diagram

The current arrow is pointing towards the negative terminal of the battery which is incorrect as current should flow out of the positive terminal.

Step3: Analyze second diagram

The current arrow is pointing out of the positive terminal of the battery and the brighter bulb has a larger arrow - tail indicating more current which is correct.

Step4: Analyze third diagram

The current arrows are inconsistent. The arrow near the battery is correct (out of positive terminal) but the arrow between the bulbs seems to be in a wrong direction considering the overall circuit flow and the brightness - current relationship.

Answer:

The first and third diagrams incorrectly convey a current concept.
