\sec \left[ {{{\tan }^{ - 1}}\left( {\frac{{b + a}}{{b - a}}} \right) - {{\tan }^{ - 1}}\left( {\frac{a}{b}} \right)} \right]

View answer and explanation

Correct option: B

\sqrt 2

Option B (

\sqrt 2

) is correct because simplifying the expression using the tangent subtraction formula and then finding the secant of the result gives this value.
