Determine the corrections or otherwise of the following assertion and reason : Assertion : Most of the tails are using symmetric airfoils. Reason: Tail control has two primary control surface. and are true and is the correct reason for b) Both and are true but is not the correct reason for c) is true but is false d) is false but is true

Determine the corrections or otherwise of the following assertion and reason : Assertion : Most of the tails are using symmetric airfoils. Reason: Tail control has two primary control surface. and are true and is the correct reason for b) Both and are true but is not the correct reason for c) is true but is false d) is false but is true Correct Answer A

Tail control has two control surface as primary control surface namely elevator and rudder. Tail has main function of providing stability and control. Hence, it should not produce lift at zero angle like wings otherwise it will affect the stability of the aircraft. Hence, and both true but is not correct reason for given .
