Solution

The correct option is B
Gene → Cistron → Recon → Muton

Gene size ranges from 20,000 to 50,000 base pairs.

Cistron is a DNA strand/segment.

Recon is the smallest section of a chromosome which is capable of recombination.

Muton is the smallest element, which when altered leads to a mutation.
