Answer:
The answer is indeed letter D. The sentence contains a typo.
Explanation:
The sentence "Unfortunately, the poor eating habits of parents are often past down to their children" has a misspelled word. "Past" can be a noun, an adjective, a preposition, or even an adverb. In general, it refers to something that happened at a previous moment in history, or it indicates location or a lapse of time.
What happened in this sentence is a common mistake. "Past" has a homophone - another word that sounds just like it, but is spelled and used differently -, "passed", which would have been the correct choice. The sentence uses the passive voice to describe how eating habits are taught. Passive voice requires the past participle form of a verb. In the case of the verb "to pass", it would be "passed". Thus, "Unfortunately, the poor eating habits of parents are often passed down to their children" would have been right.
