Question

Assertion (A): Cancer cells are virtually immortal until the body in which they reside dies.

Reason (R): Cancer is caused by damage to genes regulating the cell division cycle.

Options

• Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

• Both assertion (A) and reason (R) are true, but reason is not the correct explanation of assertion.

• Assertion (A) is true but reason (R) is false.

• Both assertion (A) and reason (R) are false.

Answer 1

Both assertion (A) and reason (R) are true, but reason (R) is not the correct explanation of assertion (A).

Explanation:

Cancer cells can divide indefinitely, and cancer involves damage or mutation of genes regulating cell division. The reason describes uncontrolled division but does not, by itself, explain the claim of virtual immortality.
