# When a positively charged block is placed near an uncharged metallic sphere, the sphere gets equal and opposite charges on its two halves, as shown in the figure.The sphere becomes charged because of

$\begin{array}{1 1}(A)\;\text{conduction}\\ (B)\;\text{insulation} \\ (C)\;\text{induction} \\(D)\; \text{friction} \end{array}$

The sphere becomes charged because of induction.
Hence C is the correct answer.
