Task: Answer the multiple choice question.
Query: Which drug has a 2.493\% 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) Cc1ccc(O)c(NC(=O)c2ccc3c(c2)C(=O)N(CC(C)C)C3=O)c1
b) O=C(NCc1nnc(SCC(=O)N2CCN(c3ccccc3)CC2)o1)c1c(F)cccc1Cl
c) O=C1CC(c2ccc(Br)cc2)NC(c2ccc(Br)cc2)C1c1ccccc1
d) COCCNc1ccc(-c2nn(C)c(=O)c3ccccc23)cc1[N+](=O)[O-]
Answer: b. O=C(NCc1nnc(SCC(=O)N2CCN(c3ccccc3)CC2)o1)c1c(F)cccc1Cl
