The carbon dioxide acceptor in Calvin cycle/C3-plants is

(A)phosphoenol pyruvate (PEP)
(B)ribulose 1,5-diphosphate (RuDP)
(C)phosphoglyceric acid (PGA)
(D)ribulose monophosphate (RMP)

The NCERT line that answers it

Verbatim line

In the carbon fixation cycle, $\text{CO}_2$ is added by the enzyme, RuBisCO, to a 5-carbon compound RuBP that is converted to 2 molecules of 3-carbon PGA.

Chapter: Photosynthesis in Higher Plants
Section: 11.10 FACTORS AFFECTING PHOTOSYNTHESIS

The answer appears as a continuous sentence in NCERT. This is that sentence.

How this line gives the answer

75, emb=0.7822, combined=0.7693). Verified: high — The span explicitly states that CO₂ is added to RuBP (ribulose 1,5-diphosphate) in the carbon fixation cycle, which directly identifies RuDP as the CO₂ acceptor in Calvin cycle/C₃ plants.
