The diagram shows three infinitely long uniform line charges placed on the \( X, Y \) and \( Z \) axis. The work done in moving a unit positive charge from \( (1,1,1) \) to \( (0,1,1) \) is equal to
(a) \( \frac{(\lambda \ln 2)}{2 \pi \varepsilon} \)
(b) \( \frac{(\lambda \ln 2)}{\pi \varepsilon_{0}} \)
(c) \( \frac{(3 \lambda \ell \mathrm{n} 2)}{2 \pi \varepsilon_{0}} \)
(d) None of these
