A spherical liquid drop of radius R is divided into eight equal droplets. If surface tension is T, then the work done in this process will be

(a) $2{\mathrm{\pi R}}^{2}\mathrm{T}$                        (b) $3{\mathrm{\pi R}}^{2}\mathrm{T}$

(c) $4{\mathrm{\pi R}}^{2}\mathrm{T}$                         (d) $2{\mathrm{\pi RT}}^{2}$
