Final answer:
The sentence with correct spelling, punctuation, and capitalization is (c) 'The beach, on the other hand, might be more fun.' This sentence correctly uses all writing mechanics.
Therefore, option C is correct.
Step-by-step explanation:
The sentence that shows correct spelling, punctuation, and capitalization is (c) The beach, on the other hand, might be more fun. This sentence is correctly capitalized, punctuated, and has all words spelled correctly. Sentence (a) incorrectly spells 'picnic' as 'picnik' and improperly capitalizes 'Park.' Sentence (b) lacks necessary punctuation after 'fact' and has comma placement issues. Sentence (d) has unnecessary commas around the proper noun 'Alicia.'
It is essential for students to be aware of their writing mechanics, which include correct spelling, punctuation, and capitalization. These elements contribute to the clarity of the writing and should be consistent, regardless of the formality of the message.
