Answer 1

Hint: Here first we have to see what is meant by cyclone alert or watch and what cyclone warning is.

Cyclone alert: A cyclone alert is an alarm given by public climate estimating bodies to waterfront territories undermined by the impending methodology of a typhoon or tropical cyclone.

Cyclone warning: Cyclone warnings are issued in different signals. A 'very peril' caution, which implies the cyclone is presently a serious or extremely serious cyclone and is required to move holding the port to one side.

Complete step by step solution:
A cyclone is an overall term for a climate framework where winds turn internally to a territory of low atmospheric pressure. For enormous climate systems, the circular design is a counter clockwise way in the Northern Hemisphere and a clockwise course in the Southern Hemisphere.
The Second Stage cautioning known as Cyclone alert is given at any rate $48$ hrs. Ahead of time of the normal beginning of unfriendly climate over the seaside territories. It contains data on the area and power of the storm likely bearing its development, strengthening, waterfront areas prone to encounter antagonistic climate and guidance to anglers, overall population, media and catastrophe chiefs.

The Third Stage cautioning known as Cyclone warning gave in any event $24$ hours ahead of time of the normal beginning of antagonistic climate over the beachfront zones. Landfall point is figured at this stage. These warnings are given by HQ at three hourly spans giving the most recent situation of cyclone and its force, likely point and season of landfall, related substantial precipitation, solid breeze and tempest flood alongside their effect and counsel to overall population, media, and disaster managers.

Hence, option D is correct.

Note:Cyclone alert and cyclone warning are given at different stages. Cyclone warning is assumed to be more dangerous than cyclone alert.
