Except option (2), all are applications of capillary action. One would not be able to consume soft drink, if there is no atmospheric pressure, i.e., in vacuum.

Explanation:
1. Difficulty in using a kerosene lamp:
Capillarity is the phenomenon by which liquids rise or fall in narrow tubes or porous materials due to the forces of cohesion and adhesion. In a kerosene lamp, the wick acts as a capillary tube. The liquid fuel (kerosene) rises through the wick due to capillary action and gets evaporated at the top, where it can be ignited to produce light. Without capillarity, the kerosene would not be able to rise through the wick, making it difficult to use a kerosene lamp.
2. Inability to use a straw to consume a soft drink:
When we use a straw to consume a soft drink, we create a partial vacuum inside the straw by closing one end with our finger and sucking through the other end. This partial vacuum causes the liquid to rise in the straw and enter our mouth. Capillarity plays a role here as well. The liquid in the straw rises due to capillary action, allowing us to consume the drink. Without capillarity, the liquid would not rise in the straw, making it impossible to use a straw to consume a soft drink.
3. Failure of blotting paper:
Blotting paper is a highly absorbent paper used to soak up excess liquid or moisture. Capillarity is responsible for the absorbent properties of blotting paper. The narrow spaces between the fibers of the paper act as capillary tubes, allowing the liquid to be drawn up and absorbed. Without capillarity, the blotting paper would not be able to function effectively in soaking up moisture.
4. Non-growth of big trees:
Capillarity plays a crucial role in the movement of water in plants. The roots of plants absorb water from the ground, and this water is transported to the leaves through the xylem vessels. Capillary action helps in the upward movement of water in the xylem vessels against gravity. This upward movement of water is essential for the growth of big trees. Without capillarity, the water would not be able to reach the upper parts of the tree, hindering its growth.
Therefore, statements 1, 3, and 4 are correct.
