Explanation

Why (b) is correct

The light harvesting complex is an array of hundreds of pigment molecules bound to proteins, which funnels absorbed energy to its reaction centre.

Why the other options are wrong

(a) · your answer It contains several pigments, bound to proteins.
(c) · your answer CO₂-reducing enzymes are in the stroma.
(d) · your answer Both PS I and PS II have a light harvesting complex.

NCERT point: Each photosystem = LHC + reaction centre.
