The effective capacitance of a capacitor is increased when the capacitors are connected in parallel. When the capacitors are connected in parallel, the equivalent capacitance is given by:
$C_p=C_1+C_2+C_3+\ldots \ldots$
When the capacitors are connected in parallel, the potential difference across each capacitor is the same.

Statement$-I:$In an ac circuit, the current through a capacitor leads the voltage across it.
Statement$-II:$ In a.c. circuits containing pure capacitance only, the phase difference between the current and the voltage is $\pi$
In the light of the above statements, choose the most appropriate answer from the options given below
| Column-$I$ | Column-$II$ |
| $a.$ Binding energy per nucleon for ${ }^{56} Fe$ | $(i)$ $5.5 \,M eV$ |
| $b.$ Energy of $\alpha$-particle in Geiger Marsden experiment | $(ii)$ $200 \,M eV$ |
| $c.$ Energy of photon of visible light | $(iii)$ $8.75 \,M eV$ |
| $d.$ Energy released in fission of a uranium nucleus | $(iv)$ $2 \,eV$ |
Reason : Laws of reflection are strictly valid for plane surfaces, but not for large spherical surface.
