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

How this line gives the answer

0, emb=1.0, combined=1.0). Verified: high — The span explicitly states 'Francis Crick proposed the Central dogma in molecular biology, which states that the genetic information flows from DNA→RNA→Protein', which directly matches the diagram's flow (DNA→mRNA→Protein) and identifies Francis Crick as the proposer, conclusively proving option A.
