Answer:
Option C, check the surface temperature of seawater
Step-by-step explanation:
Now a days, meteorologist predict the occurrence of a cyclone based on physical characteristics such as temperature of surface water of ocean, its salinity, mixing of upper ocean water etc.
Whenever a cyclone approaches towards a sea, it causes the surface water of ocean to cool down by churning of colder deeper water of oceans thereby lowering the temperature of surface water.
Option C, check the surface temperature of seawater
