Answer 1

Hint: Casual is an adjective which means not serious or very laid-back in nature.

Complete step-by-step answer:

We know the meaning of the italicized word, which is harsh, from the hint given to us. The word with the opposite meaning of casual must be the opposite of its description, that is, it should mean serious and not laid-back in nature.
Harsh means being rude and unpleasant towards someone. We observe that it does not mean the opposite of casual. Hence, option A is not the correct answer.
Systematic means being very orderly and organized. We observe that it does not mean the opposite of casual. We observe that it does not mean the opposite of casual. Hence, option B is not the correct answer.
Formal means being serious and not laid-back in nature. We observe that it is the opposite of casual and also matches the description for the opposite of casual, we had inferred. Hence, option C is the possibly correct answer
Regular is something that keeps repeating itself. It also means something that is average and normal. We observe that it does not mean the opposite of casual. Hence, option D is not the correct answer.
After having observed all the options, we conclude that option C is the correct answer.

Note: Formal also means official in certain contexts such as a formal complaint, a formal announcement, etc.
