Haryana Police Constable Model Paper 1

The pattern followed here is:
The first letter is kept constant.
From the second letter onward, the gap between a letter and its code increases by 1.
$\begin{array}{ccccccccc}\mathrm{A}& & \mathrm{B}& & \mathrm{O}& & \mathrm{D}& & \mathrm{E}\\ \downarrow +0& & \downarrow +2& & \downarrow 3& & \downarrow +4& & \downarrow +5\\ \mathrm{A}& & \mathrm{D}& & \mathrm{R}& & \mathrm{H}& & \mathrm{J}\end{array}$
Let's check each option:
(1)
$\begin{array}{ccccccc}\mathrm{A}& & \mathrm{G}& & \mathrm{R}& & \mathrm{O}\\ \downarrow +0& & \downarrow +15& & \downarrow 11& & \downarrow +15\\ \mathrm{A}& & \mathrm{V}& & \mathrm{C}& & \mathrm{D}\end{array}$
(2)
$\begin{array}{ccccccc}\mathrm{A}& & \mathrm{G}& & \mathrm{R}& & \mathrm{O}\\ \downarrow +0& & \downarrow +2& & \downarrow 3& & \downarrow +4\\ \mathrm{A}& & \mathrm{I}& & \mathrm{U}& & \mathrm{S}\end{array}$
(3)
$\begin{array}{ccccccc}\mathrm{A}& & \mathrm{G}& & \mathrm{R}& & \mathrm{O}\\ \downarrow +0& & \downarrow +2& & \downarrow 1& & \downarrow +5\\ \mathrm{A}& & \mathrm{I}& & \mathrm{S}& & \mathrm{T}\end{array}$
(4)
$\begin{array}{ccccccc}\mathrm{A}& & \mathrm{G}& & \mathrm{R}& & \mathrm{O}\\ \downarrow +0& & \downarrow +2& & \downarrow 4& & \downarrow +9\\ \mathrm{A}& & \mathrm{I}& & \mathrm{V}& & \mathrm{X}\end{array}$
