Assuming the bullet points are not negative signs,

let's look at "the sum of a number and three."

That would obviously be n+3, where n is the 'number.'

Look at the phrase again.

"Twice the sum of a number and three,"

That would be twice of n+3

2*(n+3), which is 2(n+3)

So it is the fourth answer.
