Explanations:
(d)
The correct phrase to use in this context is "to hear of." The sentence should read, "It grieved me to hear of my friend’s serious illness." This expression is commonly used to convey sadness or sorrow upon learning about someone's unfortunate situation or condition.
The other options are not idiomatic in this context:
To hear of: This is the correct and commonly used phrase to express sorrow upon learning about someone's situation.
In hearing: This phrase is not the typical way to express grief or sorrow in response to someone's illness.
To hear regarding: While "to hear" can be followed by "regarding" in some contexts, it is not the most idiomatic choice in expressing grief.
Hearing regarding: This phrase is not commonly used, and it may sound awkward in this context.
Therefore, option 1, "to hear of," is the most appropriate choice to complete the sentence.
