One of the statements below contains a word used incorrectly. Choose the option which has the incorrect or inappropriate usage of the word.

The word 'affect' means 'to cause an effect' or 'to have an effect on'. All of options A, B, and D have the correct usage of the term 'affect' in its various forms, except option C. While it is the sickness of the family member that is affecting or having an effect on the lives of the family members in option A, in option B it is the state of Kerala being affected by the floods. Option D talks about the style of acting which is said to be 'affected', here the term 'affected' refers to pretentious, or artificial, and is also a correct usage.

Option C, instead of writing 'after effects' (which is a noun), writes 'after affects', which is incorrect usage, as the word 'affect' is meant to be a verb. Therefore, option C is the correct answer.
