Solution

The correct option is D if $\to A = \to u a n d \to B = \to a t, t h e n \to C = \to v$
$(\to u, \to v, \to a a r e u s u a l s y m b o l s)$
From the diagram, $\to C = \to A + \to B$
If $\to A = \to u a n d \to B = \to a t, t h e n \to A + \to B = \to u + \to a t = \to v$
$∴ \to C = \to v$
