Answered By Charn G

Somatic cells are all the cells in the body except for the germ(sex) cells. For example, skin, eyes, and hair cells. So for the first one, prolonged skin exposure will cause damage to the individual's skin cells, therefore it will cause a mutation in the somatic cells. The second one is a sex-linked trait so it will automatically fall under germline mutation. If homologous chromosomes fail to separate in meiosis, it will be a germline mutation, as meiosis is linked with the creation of sex cells. For the last one, since it is referring to mitosis, it must be a somatic cell mutation.
