The correct option is C) 12:13 PM Monday.
Tides follow a predictable pattern. In most places, there are two high tides and two low tides approximately every 24 hours and 50 minutes. The time between a high tide and the subsequent low tide (Ebb) is roughly half the period between two consecutive high tides, which is about 6 hours and 12.5 minutes. Ebb tide is the phase when the sea level is falling.
Given that high tide occurs at 6:00 AM Monday.
The low tide following this high tide will occur approximately 6 hours and 12.5 minutes later.
6:00 AM + 6 hours 12.5 minutes = 12:12:30 PM Monday.
The ebb tide is the period from high tide to low tide. The question asks “at what time the same place will be affected by Ebb?”. This is slightly ambiguous, as ebb is a period. However, among the options, 12:13 PM is the closest time to the predicted low tide, which marks the *end* of the ebb phase and the start of the flood phase. The other options represent subsequent high tide times. Therefore, 12:13 PM Monday is the most plausible answer representing the transition point following the ebb phase.
