Answer:
<em>The correct option is B) regulation of mitosis</em>
Explanation:
Cancer can be described as a group of diseases which result from uncontrolled, abnormal cell division. The cell division by which the cells divide (except sex cells) is termed as mitosis. Hence, scientists will be studying the regulation of mitosis if they are to find a cure for cancer.
Other options like option A are not correct because only sex cells divide by meiosis. Hence, regulation of meiosis will not cure cancer.
