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 the straight-lines
\( \mathbf{r}=\mathbf{i}+2 \mathbf{j}+3 \mathbf{k}+\lambda(a \mathbf{i}+2 \mathbf{j}+3 \mathbf{k}) \) and
\( \mathbf{r}=2 \mathbf{i}+3 \mathbf{j}+\mathbf{k}+\mu(3 \mathbf{i}+a \mathbf{j}+2 \mathbf{k}) \) intersect \( \mathbf{a t} \mathbf{a} \)
point then the integer \( a \) is equal to \( -5 \).
Statement-2: Two straight lines intersect if the
shortest distance between them is zero.
