Solution

The correct option is B Centromere
  • The centromere is the lighter staining region present on the chromosome of a cell which appears as a constriction.
  • They are also known as a primary constriction or kinetochore.
  • It is a specialized DNA sequence that links a pair of sister chromatids where the spindle fibres are attached during cell division.
  • So, the correct answer is 'Centromere'.
