options are:-

1- quick lime
2- organic matter
3- slaked lime
4- magnesium hydroxide

Answer 1

Quick lime, Slaked lime and Magnesium hydroxide are basic in nature.
Organic matter produces acidic substance when it decays. So to reduce basic nature, Organic matter should be added.

Answer is 2.

Answer 2

Organic matter can be added to the soil to reduce its basic nature.

• Acidic chemicals should be applied to the soil to balance its pH if it is excessively basic.

• In order to boost soil fertility and lessen its basic character, manure and compost, also known as organic matter, must be applied to the soil.
• These substances release acids that react to neutralise excess bases in the soil.

• The use of organic materials can assist reduce the alkalinity of a soil. With proper application, this will reduce the pH of the soil, release vital nutrients, and neutralise the soil's basic nature.
• Simply put, decomposing organic waste that is acidic in nature is added to the soil to lessen its alkaline effect.

Hence, correct option is 2.organic matter.
