the first one doesn't need any puncuation.
After the book slid from my lap and landed on my foot; I realized that I had fallen asleep.
You're right about the first sentence.
I'm not sure whether you have a comma or semicolon after foot. You need a comma there.
why do i need to add a comma there
You need a comma to separate the introductory clause from the independent clause.

The sentence missing punctuation is sentence b: "After the book slid from my lap and landed on my foot I realized that I had fallen asleep." The correction necessary is to add a comma after the phrase "on my foot" to make the sentence grammatically correct.
The corrected sentence would be: "After the book slid from my lap and landed on my foot, I realized that I had fallen asleep."
The correction is necessary because the phrase "After the book slid from my lap and landed on my foot" is an introductory phrase. Introducing a sentence with a phrase requires a comma after the phrase to separate it from the main clause. Adding the comma clarifies the sentence structure and makes it easier for readers to understand the intended meaning.
