Prepositions After Adjectives

The correct answer is of. We say “cured of” an illness, not “cured with” or “cured from” or “cured against”. For example, we might say “He was cured of his cancer” or “She was cured of her cold”.

Option B is the correct answer because ‘to’ is used to indicate the relationship between one person and another. Options A, C and D are incorrect because ‘with’ is used to indicate possession, ‘by’ is used to indicate proximity or agency and ‘on’ is used to refer to an unspecific location or time.
