Answer:
The sentence includes a list of phrases that include commas.
Step-by-step explanation:
A semi-colon is a punctuation mark that is used not so often but also has its own requirements. It is mostly used in separating a list of items that has an internal comma.
In the given sentence, the list includes the items needed for the trip. And since the list includes an internal comma, it is not possible to 'punctuate' them with the same comma, which is when the semi-colon comes into use. This semi-colon will ensure the list is punctuated correctly and also provide the easy identification of items.
The use of the semi-colon in the sentence is because the sentence already includes an internal comma in it. Thus, the correct answer is the fourth or last option.
