(d)

There is no acceleration in the horizontal direction.

$S_x=U_x T+\frac{1}{2} a_0 	imes T^2$

$R=U_x T \ldots (1)$

$S_y=U_y T+\frac{1}{2} g_y T^2$

$O=V_1 T-\frac{1}{2} g T^2$

$\Rightarrow V_1 T=\frac{1}{2} g T$

$T=\frac{2 V_1}{g}$

We know,

$(R)$ range $=($ Horizontal velocity $4 x) 	imes$ flight $+$ time $(T)$

i.e., $R=4 x 	imes T$

$R=V_2 	imes \frac{2 V_1}{g} \Rightarrow \frac{2 V_1 V_2}{g}$
