a.

Explanation:

The semicolon is correctly placed before the conjunctive adverb "therefore" that is being used here to join two independent clauses, correctly followed by a comma as conjunctive adverbs introducing the second clause in a sentence should be. Option c, while it follows this rule, is wrong because it uses semicolons instead of commas to separate the list elements (i.e. places that "we" want to visit).

for this case, we must find the number of deaths per day of the year 2015, in automobile accidents, knowing that 32,400 people died.

knowing that the year 2015 had 365 days we have the following division:

where "x" represents the number of deaths per day.

rounding off we have:

approximately, 89 people per day died in 2015

answer:

89 people per day
