Option (C) is the correct answer.

Explanation:

Once the cats escaped from the puzzle box, then in their conscious mind they tend to develop the image of path through which they had escaped.

So, form next time onward they tend to move more quickly because they already know the path through which they had to escape.

Hence, we can conclude that after receiving a reward for escaping the puzzle box, the cats gradually learned to escape more quickly.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
