Some people use genetic testing before becoming pregnant to find out whether a. their child is likely to be tall. b. their child is likely to have dawn syndrome. c. they’re carriers of a genetic disorder. d. they’re able to become pregnant

C. They're carriers of a genetic disorder.

Genetic testing can help screen for variants/mutations in potential parents' DNA. If one or both parents test negative, they will know their child will not inherit the disorder. Likewise, if they both are carriers, there is a chance their child could be affected, which is helpful information in determining whether to have their own children, or how to address their child's possible disorder.
