Answer 1

c) A cyclone is formed by a very high pressure system with very high speed winds revolving around it.

Answer 2

In winter the winds indeed flow from the land to the ocean.  This statement is correct.

Option a)

Explanation:  

• In winter, when the temperature falls, the 'land loses heat' at a rate faster than the ocean. This results in the water of the ocean having a higher temperature than the land.
• The air that is present over the ocean as a result heats and rises and creates a 'low-pressure region'.
• The air present over the cold land, therefore, rushes towards the ocean to mitigate that low pressure, and this results in the winds rushing from the land to the seas in winter.
