Answer: 4)Variable

Explanation:

The primary constriction of a chromosome is the centromere. The centromere is where the chromatids are attached to each other, But the secondary constriction can be present anywhere on the chromosome apart from the centromere. Thus the position of secondary constriction is variable.

Due to secondary constriction, a knob-like structure is present at the end mostly known as a Satelite chromosome.

Nucleolus organizing region (NOR) is present in SAT chromosome.
