In fog, the signal 'one short blast, a prolonged blast, and a short blast' indicates which condition?

Explanation:
In fog, ships use specific sound patterns to tell others what they’re doing. The signal that includes a long blast with accompanying shorter blasts is the indicator that the vessel is anchored. The long blast is the key element that marks the anchorage status, and the surrounding short blasts help other mariners recognize the pattern quickly and distinguish it from signals for underway, towing, or not under command. So this pattern tells nearby vessels that this vessel is at anchor and stationary, not making way.
