B. as they grow larger, snails can tolerate progressively higher temperatures
C. smails from exposed shores grow small feet when raised on sheltered shores, but grow large feet when raised on exposed shores
D. snails tend to be warmer when the tide is out that when the tide is in
C is the example of reaction norm.
As reaction norm is expression of a individual/ phenotype/ genotype under different environmental condition.
If a reaction norm is straight, it means the organisim did not change its expression under different environmental condition.
