Solution

The correct option is B Continuous fibres
The spindle apparatus shows three types of fibres-
1. Astral which radiate out from centrioles towards plasma membrane.
2. Chromosomal or kinetochore fibres attach to the kinetochore disc of chromosome.
3. Continuous or polar fibres are not attached to the chromosomes and serve to separate the two centrioles.
