Which sentence uses a colon correctly?

for their honeymoon they went to the following places: florida, st. lucia, and the bahamas.

after dinner i washed: the dishes, the silverware, and the glasses.

the ingredients i need to make salsa are: tomatoes, cilantro, onion, garlic, and peppers.

when i retire from my job, i want to travel to: rome, italy, france, australia, and mexico.

The correct answer is,

"For their honeymoon they went to the following places: Florida, St. Lucia, and the Bahamas."

The part that comes before a colon must be a complete sentence. A good tip is to read the first part and if it sounds normal without the second part, it is correct. So if you simply wrote the phrase "The ingredients I need to make salsa are." as a sentence, it would not make sense.

answer: honestly, me too dude. i feel that.
