Answer:

The correct answer is option 4.

Explanation:

Substance which releases hydroxide ions(OH^-) in an aqueous solution are termed as bases.

Substance which releases proton (H^+) in an aqueous solution are termed as acids.

From the given options:

CH_3COOH : It is an weak organic acid known as acetic acid. Being acid it releases [H&+] ion in an aqueous solution.

CH_3COOH(aq)\rightarrow CH_3COO^-(aq)+H^+(aq)

CH_3COH : It is an alcohol named methanol and it is slightly acidic.They gives H^+ ions and alkoxiode ions.

CH_3COH(aq)\rightarrow CH_3CO^-(aq)+H^+(aq)

HCl : It is strong acid known as hydrochloric acid. Being highly acidic it releases [H&+] ion in an aqueous solution.

CH_3COOH(aq)\rightarrow Cl^-(aq)+H^+(aq)

KOH : It is strong base known as potassium hydroxide. Being highly acidic it releases [H&+] ion in an aqueous solution.

KOH(aq)\rightarrow K^+(aq)+OH^-(aq)

Tides describe the regular rising and falling of ocean water. Tides are caused by
user100 [1]

Tides are the rise and fall of the oceans. They are caused by the gravity, or pull, of the Moon and Sun. The Moon's gravity is the main force in causing tides. It makes the oceans bulge out toward it. Another bulge occurs on the opposite side, because Earth is being pulled toward the Moon and away from the water. The water on the side farthest away from the Moon is least affected by its gravity.
