which choice completes the text with the most logical transition?
choose 1 answer:
a on the contrary,

Explanation:

The first sentence explains that desert plants have thick, waxy coatings on their leaves to prevent water evaporation. The second sentence states that the plants lose very little water to the dry air. There is a cause - and - effect relationship here.
