Assertion (A): √3 + √5 is indeed irrational.If it were rational, say r, then √5 = r − √3.Squaring both sides gives 5 =$r^{2}$ + 3 − 2r √3, which implies √3 = $\frac{r^{2} - 2}{2r}$.Since the RHS is rational and √3 is irrational, this is a contradiction.Thus, (A) is true.Reason (R): This statement is false.Counter-example: Consider two irrational numbers √2 and − √2.Sum: √2 + (−√2) = 0, which is a rational number.Since the Reason is false, the option is (C)Assertion (A) is true, but Reason (R) is false
