(II) The race car builder and his teammates are spending the weekend trying to discourse their prototype and build a better model.
(III) The news article aims to discourse the public about the latest developments in the field of renewable energy.

Correct option is B

The correct statement is “statement (I)”, “A major disadvantage of online discourse is that people can often say whatever they like in complete anonymity.”
Discourse: written or spoken communication or debate.
The statement correctly uses the word "discourse", which means in the context of online communication. It highlights the negative aspect of online discourse, where individuals can express themselves freely, often without any accountability, due to the anonymity provided by online platforms.
The incorrect options are:
(II) The race car builder and his teammates are spending the weekend trying to discourse their prototype and build a better model.
Explanation: The usage of "discourse" in this sentence is incorrect. In this context, the word "discourse" should be replaced with a more appropriate term such as "refine," "improve," or "develop." The sentence implies that the race car builder and the teammates are engaged in the process of working on their prototype to enhance its design.
(III) The news article aims to discourse the public about the latest developments in the field of renewable energy.
In sentence (III), the word "discourse" is used incorrectly. The sentence reads: "The news article aims to discourse the public about the latest developments in the field of renewable energy."
The correct usage of "discourse" in this context would be to replace it with "inform" or "educate."
