    Since we have present simple in 1st part of the sentence, B, D & E are correct (most matching answer is E)

    That was the 1st time, (1) I've done/ (2) I did .....
    (1) if it is still your 1st time up till now (did it once)
    (2) if you've done it again many times after,

    Hope i helped
