E, F, G, H, J, K and L are sitting around a circular table facing the centre of the table (but not necessarily in the same order).Only one person sits between E and L when counted from the left of L. K sits third to the right of J. F sits third to the left of G. K sits to the immediate right of F. H is not an immediate neighbour of F. How many people sit between H and L when counted from the right of H?

Given: 

E, F, G, H, J, K and L are sitting around a circular table facing the centre of the table (but not necessarily in the same order).

Only one person sits between E and L when counted from the left of L.

K sits third to the right of J.

F sits third to the left of G.

K sits to the immediate right of F.

H is not an immediate neighbour of F.

Three people sit between H and L when counted from the right of H.

Thus, correct option is (a).
