Task: Answer the multiple-choice question.
Query: Which compound exhibits a 9.769\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) O=C(CN1CCC(O)(c2ccccc2F)CC1)NCCc1c[nH]c2ccccc12
b.) Cc1ccc2c(c1)C(c1ccc(F)cc1)N(C(=O)c1cc3ccccc3oc1=O)CC(=O)N2
c.) O/N=C(\C[n+]1ccccc1)c1ccc(Br)cc1.[Br-]
d.) COc1ccc(NS(=O)(=O)c2cc(NC(=O)[C@@H](NC(N)=O)C(C)C)ccc2C)cc1
Answer: a. O=C(CN1CCC(O)(c2ccccc2F)CC1)NCCc1c[nH]c2ccccc12
