B. $\left[ {A{T^{ - 1}}} \right]$
C. $\left[ {A{T^{ - 2}}} \right]$
D. $\left[ {A{T^2}} \right]$

Answer 1

Hint: Charge is the fundamental property of types of matter which, in presence of another matter, exhibit electrostatic attraction or repulsion. Electric charge is a function in certain subatomic particles. The charges of stand-alone particles are the integer numbers equal to the elementary charge.

Step-By-Step answer:
Michael Faraday first discovered the distinct existence of electrical charge in his electrolysis studies. This was illustrated specifically by the oil drop experiment by Robert Millikan and the specific charge was calculated. A macroscopic object's electrical charge is the sum of the electrical charges of its components. This cost is also low since electrons are the same as the others, while their charges are canceled resulting in a total charge of 0 and rendering the atom neutral.
The ion is an atom (or the atoms) containing one or more electrons that have gained a net positive charge (cation), or one or more electrons that have retained the net negative charge (anion), which is a net negative charge. Monatomic ions are created from single atoms, whereas polyatomic ions are generated from two or more bound atoms that create a positive or negative net load in each case.
It's S.I. unit is coulomb and its dimensional formula is-
$ \Rightarrow \left[ {{M^0}{L^0}{T^1}{A^1}} \right]$
Where, M is mass, L is length, T is time and A is current.
Hence, option A is the correct option.

Note: The charge drawn from one material is passed into the other material leaving behind an opposite charge of the same amount. The charging rule still exists, allowing for a positive charge of equivalent value and vice versa for the object against which a negative charge is obtained.
