Determine the corrections or otherwise of the following assertion [A] and reason [R]:Assertion [A]: To generate new airfoil, we use spanwise line instead of chord line in flat wrap interpolation technique.

• A. nReason[R]: Chordwise line will generate flat structure from curves having different values of tangent angle.
• B. Both [A] and [R] are true and [R] is the correct reason for [A]
• C. Both [A] and [R] are true but [R] is not the correct reason for [A]
• D. Both [A] and [R] are false
• E. [A] is true but [R] is false
