Question

sita died ________breast cancer. With,by,of,for​

Answer 1

Answer:

Sita died of breast cancer.

Answer 2

The correct answer will be Sita died "of" breast cancer.

"For" is used with the object or in purpose of something or someone.

Here sita does not die in the purpose of cancer hence it's wrong.

"With" is used to show accompaniment, to accompany something or someone.

Here sita does not accompany cancer in dying hence it's wrong.

"By" is used when something or someone is used as a means of something.

Here, sita does not use cancer as a means of dying hence it is slightly wrong.

"Of" is used when something is the cause of another.

Here cancer is the cause of Sita dying.

Hence of will be the most appropriate answer.
