Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 4.138\% 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: Cc1cc(C)cc(COc2ccc3c(C)c(CC(=O)O)c(=O)oc3c2C)c1
b: Cc1cccc(N2CCN(Cc3nc(CC4CC4)no3)CC2)n1
c: COc1ccc(C2N3CC(C)(C)CN23)cc1
d: Br.O=C(Cn1c(NCCCO)nc2ccccc21)c1cccc(Br)c1
Answer: d. Br.O=C(Cn1c(NCCCO)nc2ccccc21)c1cccc(Br)c1
