Answer 2

Option (c)$10^{-1}$

Explanation:

The basic unit of electric charge in SI is coulombs ( C ).

The basic physical unit of electric charge in the cgs-emu system of units.

1 emu = 10 C

or

$1 C=\frac{1}{10} emu$

As per question,

1 C = X emu

So from above,

$X=\frac{1}{10} =10^{-1}$

Thus, option c is correct.
