As $\(R Q \| N O\)$, we get angle $\(N O M=\)$ angle $\(P R Q\)$ ( $\(=\)$ Corresponding angles) i.e. angle PRQ = c

Now, angle a is an exterior angle of triangle PQR , so we get $\(\mathrm{a}=\)$ angle $\(\mathrm{PQR}+\)$ angle $\(\mathrm{PRQ}=\mathrm{b}+\mathrm{c}\)$ (Exterior angle of a triangle is equal to the sum of the interior opposite angles)

Hence column A has same quantity as column B, so the answer is (C).
