Determine the corrections or otherwise of the following Assertion [A] and Reason [R]:Assertion [A]: For longitudinal static stability of an aircraft, slope of moment curve should be negative.Reason[R]: Positive slope will result in more static stability than negative slope. Hence, slope should be positive always.

• A. Both [A] and [R] are true and [R] is the correct reason for [A]
• B. Both [A] and [R] are true but [R] is not the correct reason for [A]
• C. [A] is true but [R] is false
• D. [A] is false but [R] is true
