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: If \( a, b, c \in \mathbf{R} \) and \( 3 c4 a+4 b \) and \( a0 \)
the equation \( a x^{2}+2 b x-3 c=0 \) has no real roots, then \( c0 \).
Statement-2: If \( a, b, c \in \mathbf{R} \), the equation \( a x^{2}+b x \) \( +c=0 \), has no real roots if \( b^{2}-4 a c0 \).
