The units of capacitance are

$$ rac{{{ ext{Volt}}}}{{{ ext{Coulomb}}}}$$
$$ rac{{{ ext{Coulomb}}}}{{{ ext{Volt}}}}$$
$${ ext{Ohm}}$$
$$ rac{{{ ext{Henry}}}}{{{ ext{Wb}}}}$$

The correct answer is B. $\frac{{{\text{Coulomb}}}}{{{\text{Volt}}}}$.

Capacitance is the ability of a body to store an electric charge. It is measured in farads (F). One farad is the capacitance of a capacitor that has a charge of one coulomb when a potential difference of one volt is applied across it.

Option A is incorrect because it is the units of electric potential.

Option C is incorrect because it is the units of electrical resistance.

Option D is incorrect because it is the units of inductance.
