d) Neither A nor B

Answer 1

The correct statement about colchicine is that it inhibits the formation of spindle fibers.

Step-by-step explanation:

The correct statement about colchicine is: a) It inhibits the formation of spindle fibers. Colchicine binds tubulin and inhibits the binding of spindle fibers to the chromosome, which arrests the cell cycle and prevents cell division. This mechanism is used to treat conditions such as gout and certain types of cancer.
