Of vs. From? (People die of/from serious diseases.)

[Hothu]

Hello everybody,
One thing makes me confused. Please help me!!!
Q: Choose the best answer for the sentence:
Nowadays more and more people die ......... serious diseases.
A. of B. in C. with D. from
In Oxford Dictionary, I find 'die of (a disease)= die from (a disease)'
Please let me know which option is the best and why.
Thanks in advance.

Both are fine, actually. Very strict grammarians like 'of'.

Are the following sentences correct?

He died of Cancer.
He died of a heart-attack.
He died from injuries.
He died from sunstroke.
He died from hard work :-)

Yes, but 'heart attack' is not hyphenated and 'cancer' is not capitalized.

Mr. Micawber, is it acceptable to say, " He died from an heart attack.?

'A heart attack'? Oh, some grammarians might complain, but I think you could sneak that by most any layman.

Ms Google says:

113,000 for "died from a heart attack"
720,000 for "died of a heart attack"
