- V可能形(辞書形) + ものなら
- V意向形 + ものなら
讲解
There are two uses. (1) Potential form + ものなら: "if it were possible" about something very hard to realize, followed by a wish (〜たい) or a challenge (〜てみろ). できるものなら is common. (2) Volitional form + ものなら (〜ようものなら): "if one were to do such a thing," followed by a serious or unpleasant result. Both are stronger than a plain 〜たら.

注意
It does not attach to the dictionary form of a verb with no sense of possibility (✗ 雨が降るものなら). 〜ようものなら is normally followed by a bad or serious result.

答案与解析

答案: 3 遅れようものなら
"If we were late for the deadline by even one day, we would lose our clients' trust." A bad result follows, so volitional form + ものなら is used. ものなら does not attach to the た-form or ない-form, and 遅れる has no potential meaning.
