The shape of chloroform molecule is

The $CHC{l}_3$ contains $s{p}^3$ hybridization and exhibits a tetrahedral structure.

When a molecule's core atom has four bonds and no lone pairs, the molecule is said to be tetrahedral. 

The four corners of a tetrahedron contain the atoms bound to the center atom, and there are 109.5° angles between them.

The strucutre of chloroform is as follows.

Hence, the correct option (A). Tetrahedral.
