Suppose you are invisible for a day, how will you enjoy every moment of the day?​

What I would do is explore the city I live in more and go to  a carnival and watch the sunset while on a ferris wheel. I would also realize how good to feel to be around people, but also how it truly feels being alone even if its for only 24 hours.

I will spend my time by spying on my gf is she is cheating on me or not

There should be a comma after weekend.

Explanation:

Punctuation is the use of different grammatical signs that shows the correctness of a given sentence. These punctuation marks are used in different ways, according to their own uses. They may be the comma, the semicolon, inverted commas, full-stop, etc.

In the given sentence, the use of the commas to differentiate the different duration is correct. But at the same time, the comma must also be placed next to "weekend" to make the sentence a free-flowing one. It also acts as a separation for two or more lists in a sentence.

Thus, the correct answer is the fourth option.
