Problem statement: Answer the multiple choice question.
Query: Which drug has a -0.051\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CCOC(=O)CSc1nnc(-c2nnc(SCC(=O)OCC)n2CC)n1CC
b: O=C(c1ccccc1)c1ccc(N2CCCC2)cc1
c: COc1ccccc1Nc1nc(N)nc(CSC(=S)N2CCCCC2C)n1
d: COc1ccc(O)c(-c2cc(-c3ccccc3[N+](=O)[O-])[nH]n2)c1
Answer: b. O=C(c1ccccc1)c1ccc(N2CCCC2)cc1
