Correct option is C
Correct Answer: (c)
Explanation:
All vascular plants (Tracheophytes) contain chlorophyll a and b as the main photosynthetic pigments, allowing efficient light absorption during photosynthesis.
Information Booster:
Vascular plants have xylem and phloem for conduction.
Chlorophyll a is essential for light reactions; chlorophyll b is an accessory pigment.
Secondary growth occurs only in dicots and gymnosperms.
Some vascular plants like Marsilea are aquatic.
Pteridophytes are vascular but non-seed plants.
Additional Information (Incorrect Options):
(a) False – some vascular plants are aquatic.
(b) False – not all show secondary growth.
(d) False – not all are seed-bearing (pteridophytes lack seeds).
