Relying on an animal to come by is risky. A flower may have to wait a long time for the right animals to come by. What if one never passes close enough to the flower? Hoping the wind will blow is also risky for a plant. What if the wind does not blow? What if the blowing pollen does not land on another flower? The wind could even blow the pollen over the ocean where it is wasted. Giving free nectar is costly. It is not a good use of the plants energy. A plant uses a lot of energy to produce nectar. Some animals may just drink the nectar. They may not carry off any pollen in return. To improve their chances, plants evolved special traits. For example, they developed ways to hide their nectar. Only certain animals were able to get at the plants hidden nectar. These specific animals might be more likely to visit only flowers of the same species. This was also a benefit for some animals. Animals also evolved special traits to get to the nectar. 
Question: What is risky for a plant with its nectar? 
Is it It might dry up?
No
The context mentions that plants use nectar to attract animals. However, the question asks what is risky with its nectar, which suggests a more negative connotation of relying on an animal for help in pollination rather than a positive one as was indicated by the idea of attracting them through offering free food.
Furthermore, it seems unlikely why any plant would be concerned about their flowers drying up since they are unable to move and therefore cannot do anything without help from external forces such as wind or rain. Lastly, there is no mention regarding any risks involved with letting the flower dry up so this answer does not seem feasible either based on information given in text provided nor according to common knowledge.
