Answer
The most suitable choice of process and description is thus option d.### Process (1): mitosis### Description (2): not be inherited by the children of the sunbather
Explanation
## Step1: Meiosis and Mitosis are two modes of cell division. While \"mitosis\" results in two genetically identical daughter cells from a parent cell which is typically used for body tissue growth and recovery, \"meiosis\" is employed to produce reproductive cells - eggs or sperm - for sexual reproduction. ## Step2: If mutations occur in \"mitosis\", they remain confined inside the individual's body, and do not get passed onto next generations due to its role in nonreproductive/somatic cells, i.e., they do not impact the cells used in sexual reproduction (germ cells). ## Step3: Contrarily, if mutations occur during \"meiosis\", they can be potentially passed onto the offspring, noting that this process involves reproductive cells.## Step4: In while, following the prolonged exposure to the sun scenario, it is DNA found in the skin cells that will mutate. The sunbather's skin cells are nonreproductive / somatic cells, the mitosis modality is what passes mutations along to the daughter cells.## Step5: However, these mitotic mutations won't be passed onto offspring as stated previously that it only propagates within an individual's nonreproductive cells. Therefore,
