Question

Assertion 'A' and Reason 'R' are given below. Study them and choose the correct answer from the codes given below:

Assertion (A): Lightning conductors prevent buildings from damages.
Reason (R): It passes the charge to the earth.

Codes:

  1. Both A and R are true and R is the correct explanation of A
  2. Both A and R are true but R is not the correct explanation of A
  3. A is true but R is false
  4. A is false but R is true

Answer:

Option A: Both A and R are true and R is the correct explanation of A

Detailed Solution:

The correct answer is “Both A and R are true and R is the correct explanation of A”.

Lightning conductors do indeed prevent buildings from damage.

They achieve this by providing a safe path for the electrical charge from a lightning strike to flow into the ground, rather than passing through the building and causing damage.
