Assertion (A): $$\int_\limits2^8 \frac{\sqrt{10-x}}{\sqrt{x}+\sqrt{10-x}} d x=3$$
Reason (R): $$\int_\limits a^b f(x) d x=\int_a^b f(a+b-x) d x$$
- A(a) Both (A) and (R) are true and (R) is the correct explanation of (A).
- B(b) Both (A) and (R) are true, but (R) is not the correct explanation of A.
- C(c) (A) is true and (R) is false.
- D(d) (A) is false, but (R) is true.
