Answer 1

B is NaOH. The litmus paper turns blue and this is an indication of a base.

A is HCN. The litmus paper turns red, indicating an acid but the bulb does not glow because there are very few H+ ions to conduct electricity.

C is HCl. The litmus paper turns red and the bulb glows, indicating a strong acid.
