Answer 2

The acid which is highly soluble in water is called 3) Alkali.

Solubility of alkali in water

• Alkali acids such as HCl are highly soluble in water due to the polar interactions.
• HCl has well-defined polarity. It combines with a water molecule to give a hydronium cation ($H_{3}O^{+}$)  and chloride anions($Cl^{-}$).
• For this reason, acid rains are so prevalent. HCl solubilises with rain droplets and comes down as rain high in pH.

Incorrect options

• Acids have low solubilities depending on the type of acid so option 1) Acids is not correct.
• Salt might ionize in water readily but does not have a high solubility so option 2) Salt is incorrect too.
• Depending on their polarity, salts may be soluble or insoluble in water. Thus, option 4) Solvent is incorrect as well.
