  3. No entry for bicycles.
  4. Correct answer: No entry for motorcycles.

Why this is the answer

The correct answer in the official bank: No entry for motorcycles.

A round sign with a red border and a white background is a prohibitory sign. Here a motorcycle is drawn, so entry of motorcycles into the road section is prohibited. It is not a sign that prohibits entry of all motor vehicles, and it is not the sign that prohibits entry of bicycles, which shows a bicycle without a motor.
