In the given scenario, a drought wipes out the plants, which are a critical food source for Birds A and C, since they both eat plant seeds. Bird B drinks flower nectar, which would also be affected by the drought as flowers typically die without water.
Here's a breakdown of the potential outcomes:
- Bird A: relies on insects and plant seeds. With the absence of plant seeds due to drought, it may struggle to find enough food, especially if insects are also affected.
- Bird B: relies on flower nectar. With flowers wiped out, Bird B will have no food source and is likely to die.
- Bird C: primarily eats plant seeds. Like Bird A, Bird C will also struggle to find food without seeds.
Given this analysis, the most likely outcome is that Bird A and Bird C would struggle significantly, while Bird B would also die from lack of food. Therefore, the most appropriate response would be:
"Bird B survives; both birds A and C die."
However, since Bird B can't survive without nectar, the best conclusion is that all of the birds would likely die due to the loss of their respective food sources. If the options must indicate survival for one bird, then the closest choice fitting the likely scenario provided would be one that recognizes the severe impact of the drought on all three birds.
