Solution

The correct option is C Alkaloid
Colchicine which prevents spindle formation is chemically an alkaloid. Colchicine is a mitotic inhibitor. A mitotic inhibitor is a drug that inhibits mitosis, or cell division. These drugs disrupt microtubules, which are structures that pull the cell apart when it divides. Mitotic inhibitors are used in cancer treatment, because cancer cells are able to grow and eventually spread through the body (metastasize) through continuous mitotic division and so are more sensitive to inhibition of mitosis than normal cells.
So, the correct answer is 'Alkaloid'
