Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 1.565\% 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, d, or e without using any other words.
Options:
a: O=c1c2c(nc3c(-c4ccccc4)c[nH]n13)CCCC2
b: O=C(COC(=O)c1cc(Br)ccc1O)NC1CCCCCC1
c: OC(Cn1cncn1)c1ccc(Cl)cc1
d: O=C(Nc1ccnn1C1CCN(Cc2ccc3nonc3c2)CC1)c1cccc(F)c1
e: Cc1ccc(CN2CCN(/N=C/c3cc(Br)cc(Br)c3O)CC2)c(C)c1
Answer: b. O=C(COC(=O)c1cc(Br)ccc1O)NC1CCCCCC1
