Determine the correctness or otherwise of the following Assertion [a] and the Reason [r].
Assertion: Fast decoupled load flow method gives approximate load flow solution because it uses several assumptions.
Reason: Accuracy depends on the power mismatch vector tolerance.
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) [a] is false and [r] is true.
