The answer is (A): A lunar neap tide.
Explanation for each option:
(A) A lunar neap tide: This is the correct answer because a neap tide occurs when the difference between high and low tide is the least, which does not support the formation of a tidal bore. Tidal bores require a significant tidal range to form.
(B) A large tidal range: This is incorrect because a large tidal range is a crucial factor in the formation of a tidal bore. The significant difference between high and low tides provides the necessary energy for a tidal bore to occur.
(C) Incoming tides funneled to a narrow area through a broad bay: This is incorrect because when tides are funneled into a narrow area, it can amplify the tidal wave, supporting the formation of a tidal bore.
(D) The incoming tide is funneled into a shallow and narrow area like a channel or inlet: This is incorrect because funneling the tide into a shallow and narrow area can increase the height and speed of the tidal wave, which is conducive to the formation of a tidal bore.
In summary, a lunar neap tide does not support the formation of a tidal bore due to the minimal tidal range associated with it.
