Task: Answer the multiple choice question.
Question: Which drug exhibits a 7.437\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) O=C(O)/C=C/c1ccc(O)c(O)c1
b) COc1ccc(C(c2c(O)cc(C)oc2=O)c2c(O)cc(C)oc2=O)cc1
Answer: b. COc1ccc(C(c2c(O)cc(C)oc2=O)c2c(O)cc(C)oc2=O)cc1
