Each question in this section has four choices (a), (b), (c) and (d) out of which only one is correct. Mark your choices as follows:
(a) STATEMENT-1 is True, STATEMENT-2 is True; STATEMENT-2 is a correct explanation for STATEMENT-1
(b) STATEMENT-1 is True, STATEMENT-2 is True; STATEMENT-2 is NOT a correct explanation for STATEMENT- 1
(c) STATEMENT- 1 is True, STATEMENT-2 is False
(d) STATEMENT-1 is False, STATEMENT-2 is True
Statement-1: In a \( \triangle A B C, r_{1}+r_{2}+r_{3}-r=4 R \)
Statement-2: \( r_{1} r_{2}+r_{2} r_{3}+r_{3} r_{1}=\Delta^{2} \)
