I came across this question in a test:
The father regretted _____ his children how he regretted _____ hard when he was young.
A. to tell; not to study
B. telling; not studying
C. to tell; not studying
D. telling; not to study
I know it’s either B or C and I’m inclined towards B. But can “regretted to tell” mean telling something embarrassing here?
