We walked through the Red Oak Nature Center today; it was surprising how many bicyclists were there.

Explanation:

Out of the four sentences provided, the correct punctuated sentence is the third option.

We walked through the Red Oak Nature Center today; it was surprising how many bicyclists were there.

In the first sentence, We never found the answer to our question, in fact, we’re still looking to this day, there should be a full-stop just after 'question'.

In the second sentence, The play was an actual wedding party, the actors were funny, outgoing, and playful party guests who interacted with the audience, the use of comma right after 'wedding party' should be replaced by a full stop. It will make it a much better sentence framing, shortening the sentence and also the first sentence can stand as a full sentence on it's own.

The the fourth sentence, It was an extremely hot day, 99 degrees with a heat index of over 100 degrees, the use of the comma in between day and 99 is wrong.
