D.

Whats the answer

Answer 1

B. The wool and silk were attracted to each other.

Step-by-step explanation:

When a negatively charged object, such as the wool, is held close to a positively charged object, such as the silk, an electrostatic force of attraction is generated between them due to the opposite charges. This force causes the objects to move towards each other, so the wool and silk would be attracted to each other. Therefore, option B describes what happened when the student held the wool and silk close to each other.
