Task: Answer the multiple-choice question.
Query: Which drug exhibits a -4.130% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: C=CCOc1ccccc1/C=C/C(=O)O
b: COc1ccc(C(=O)NNC(=O)C(=O)/C=C(\O)c2ccc(C)cc2)cc1
c: O=C(CN1CCOCC1)Nc1c2c(nc3ccccc13)N(Cc1ccccc1)CC2.O=C(O)C(=O)O
Answer: a. C=CCOc1ccccc1/C=C/C(=O)O
