The assertion and reason both appear to be correct.

Mutations can be caused by mutagens, which are physical or chemical agents that can alter DNA structure. Mutations can result in changes in the genetic code, which can affect gene expression, and lead to changes in protein structure and function. These changes can result in genetic disorders that can be inherited or arise sporadically.

For example, mutations in the BRCA1 and BRCA2 genes are known to increase the risk of breast and ovarian cancer. Mutations in the CFTR gene can cause cystic fibrosis, a genetic disorder that affects the respiratory, digestive, and reproductive systems. Mutations in the hemoglobin gene can cause sickle cell anemia, a blood disorder that affects red blood cells.

Therefore, mutations caused by mutagens can lead to genetic disorders.

Option a is the correct answer.
