Assertion : A brass tumbler feels much colder than a wooden tray on a chilly day. Reason : The thermal conductivity of brass is more than the thermal conductivity of wood.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false.

Correct answer

A. If both assertion and reason are true and reason is the correct explanation of assertion

Step-by-step solution

Both the assertion and reason are correct because the conducting brass tumbler absorbs heat from the body. The hand feels cold when the tumbler is touched.
