Three concentric metallic spherical shell \( \mathrm{A}, \mathrm{B} \) and \( \mathrm{C} \) or radii \( \mathrm{a}, \mathrm{b} \) and \( \mathrm{c}(\mathrm{a}\mathrm{b}\mathrm{c}) \) have surface charge densities \( -\sigma,+\sigma \), and \( -\sigma \) respectively. The potential of shell A is :
\( \mathrm{P} \)
(A) \( \left(\sigma / \varepsilon_{0}\right)[a+b-c] \)
(B) \( \left(\sigma / \varepsilon_{0}\right)[a-b+c] \)
(C) \( \left(\sigma / \varepsilon_{0}\right)[\mathrm{b}-\mathrm{a}-\mathrm{c}] \)
(D) none
