The correct answer is 2 meter however when I selected that I was told that it was incorrect. Perhaps because they have two meters twice as an answer.

I just sent them an email alerting them to the error - likely one of a number they'll receive. In the past they went back and credited everyone who answered correctly. For the record, I was marked wrong with C, the first of the two 2-meter answers, so D might get the prize.
