Select the sentence that is written in standard, formal english.

a. we went a-fishing last saturday.

b. i'm feeling real good.

c. without mitigation, the conference deteriorated into a full-fledged hullabaloo.

d. jason likes rice.

C. Without mitigation, the conference deteriorated into a full-fledged hullabaloo.

Explanation:

The answer is "C" because in the sentence "Without mitigation, the conference deteriorated into a full-fledged hullabaloo" there is a use of formal words such as mitigation, deteriorated, full-fledged hullabaloo. We can say the same with other words using an informal language:

"The conference was a complete disaster."

You can use informal language when you are talking to your family or friends but you can't use informal language when you are writing an essay.
