Antimetabolites are used to treat various cancers and

a. inhibit certain metabolites.
b. have a slower effect on rapidly growing cancer cell than normal healthy cells.
c. work by binding dna to halt rna synthesis.
d. prevent normal replication of dna.

The right answer is A.

Antimetabolites are used as a drug that disrupts metabolism (chemical processes necessary for the functioning, growth and reproduction of normal and cancer cells). These molecules have a structure similar to those of metabolites, there will be a competition between metabolites and antimetabolites to bind to enzymes.

Antimetabolites are used as a cancer treatment to destroy cancer cells.
