Correct Answer  Option 2 : Electric Charge
Concept:
Dimensional Formula
 It depicts the way to relate any unit to fundamental Units.
 If we have to find The dimensional formula of any quantity.
 At first, we find its units in terms of these fundamental units, and then replace units with these dimensions.
Dimensional Formula of Fundamental Units are
Physical Quantity

SI Unit

Dimension

Mass

Kg

M

Time

Second

T

Length

Meter

L

Current

Ampere

A

Temperature

Kelvin

K

Explanation:
 A is the dimension of current, and T is the dimension of time.
 AT is the dimension of the unit, which is the multiplication of current and time.
 Current is charge flowing per unit time.
I = q / t
So, q = I × t
The charge is the product of current and time.
So, the correct option is electric charge.
