Task: Answer the multiple choice question.
Query: Which drug exhibits a 9.842\% 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 additional words.
Options:
[a] O=C(Nc1ccc2oc(-c3ccncc3)nc2c1)c1ccc(Br)o1
[b] Cc1c(OCC(=O)N2CCC(C(=O)O)CC2)ccc2c1oc(=O)c1ccccc12
[c] Cc1cccc(NC(=O)CCc2nc3sc4c(c3c(=O)[nH]2)CCCC4)c1
[d] Cc1ccc(N(C)C(=O)c2ccc(CNc3c(N4CCC(C)CC4)c(=O)c3=O)cc2)cc1
Answer: a. O=C(Nc1ccc2oc(-c3ccncc3)nc2c1)c1ccc(Br)o1
