Explanation

Bacteriochlorophylls are specialized pigments of photosynthetic bacteria and include forms such as bacteriochlorophylls a, b, c, d and e. Chlorophyll a is the major pigment of oxygenic photosynthetic organisms, not a bacteriochlorophyll, so option c is the exception. Students may choose chlorophyll d because it is less familiar, but it is included among the bacteriochlorophyll types.
