Answer :
The statement that is FALSE is the A), that mutations must be present in parents and then passed to off srping. Mutations results from random errors in the replication of the DNA and some mutations can be inherited but others no. So mutations are not necessarily present in parents.
Mutations must be present in parents and then passed to offspring. It IS possible for parents to pass on a mutation, if there is an error in meiosis or in the processes that create sperm or eggs. But mutations may arise directly in the offspring's DNA.
