Determine the correctness or otherwise of the following Assertion [a] and the Reason [r].
Assertion: In a pure metal weld, elastic modulus in the heat affected zone (HAZ) is the same as that in the base metal.
Reason: Coarse grained microstructure in the HAZ results in lower hardness.

A) Both [a] and [r] are true and [r] is the correct reason for [a] B) Both [a] and [r] are true and [r] is not the correct reason for [a] C) Both [a] and [r] are false D) [a] is true but [r] is false
