Read Assertion (A) and Reason (R) carefully :

Assertion (A) : Mixture of cow dung and mud is used to coat the floor of houses.
Reason (R) : Cow dung helps to regulate the temperature inside the house and keeps the insects away.

Choose the correct option.

  • A.Both A and R are true and R is the correct explanation of A.
  • B.Both A and R are true but R is not the correct explanation of A.
  • C.A is true but R is false.
  • D.A is false but R is true.

Answer: A

Both A and R are true, and R is the correct explanation of A.

In many villages floors and walls are coated with a mixture of mud and cow dung. The coating helps keep the inside of the house cool in summer and warm in winter, and it is believed to keep insects away.

Those properties are exactly why the mixture is used, so R explains A, and neither statement is false.
