ACausing all cells to divide simultaneously
BProducing all proteins in the cell
CEliminating cells between developing digits — so we form separate fingers and toes rather than webbed hands and feet
DReplacing all bones with cartilage
Answer & Solution
Correct answer: C. Eliminating cells between developing digits — so we form separate fingers and toes rather than webbed hands and feet
Per NCERT 'Ready to Go Beyond', PCD removes interdigital cells so we have separate fingers. The other options misstate PCD's role.
