A series combination of `n_(1)` capacitors, each of value `C_(1)`, is charged by a source of potential difference `4 V`. When another parallel combination of `n_(2)` capacitors, each of value `C_(2)`, is charged by a source of potential difference `V`, it has same (total) energy stored in it, as the first combination has. the value of `C_(2)`, in terms of `C_(1)`, is then
A. `(2C_(1))/(n_(1)n_(2))`
B. `16 n_(1)/n_(2) C_(1)`
C. `2 n_(2)/n_(1) C_(1)`
D. `(16 C_(1))/(n_(1)n_(2))`
