Final answer:
The correct answer to complete the analogy 'son is to ____ as daughter is to mom' is 'dad', as it correctly pairs the child with their same-gender parent.
Step-by-step explanation:
To complete the analogy: 'son is to dad as daughter is to mom', we are looking for a parental pair that is parallel to the child and parent relationship mentioned in the first half of the analogy. In this case, we are comparing a son to his male parent ('dad') and thus should compare the daughter to her female parent ('mom'). The correct answer is (c) dad, since it correctly completes the analogy by connecting the child with their same-gender parent.
