Consider a rectangular cardboard box of height 3, breadth 4 and length 10 units. There is a lizard in one corner $A$ of the box and an insect in the corner $B$ which is farthest from $A$. The length of the shortest path between the lizard and the insect along the surface of the box is\\
(a) $\sqrt{5^{2} + 10^{2}}$\\
(b) $\sqrt{7^{2} + 10^{2}}$\\
(c) $4 + \sqrt{3^{2} + 10^{2}}$\\
(d) $3 + \sqrt{4^{2} + 10^{2}}$
