Problem statement: Answer the multiple-choice question.
Question: Which drug has a 6.427\% 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) Cc1c(-c2ccc(Br)cc2)[n+](=O)c2c(n1[O-])CCCCC2
b) O=C(COC(=O)/C=C/c1ccccc1[N+](=O)[O-])NC1CC1
c) CCCCc1cc(=O)oc2cc(C)cc(OCC(=O)N3CCC(C(=O)O)(c4ccccc4)CC3)c12
d) Cc1ccc(C2(c3noc(CN4CCC(C(=O)N5CCOCC5)CC4)n3)CCCC2)cc1
Answer: b. O=C(COC(=O)/C=C/c1ccccc1[N+](=O)[O-])NC1CC1
