Problem statement: Answer the multiple choice question.
Question: Which drug has a 20.640\% 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: O=C1C(=O)N(CCN2CCOCC2)C(c2ccc(F)cc2)/C1=C(/O)c1ccc(S(=O)(=O)N2CCOCC2)cc1
b: CCOC(=O)c1c(-c2ccccc2)oc2ccc(OCC(=O)O)cc12
c: C[N+]1(C)CCC(OC(=O)C(c2ccccc2)c2ccccc2)CC1.[I-]
d: Cc1ccc(-c2nn3c(C)nnc3c3ccccc23)cc1S(=O)(=O)NCCO
Answer: a. O=C1C(=O)N(CCN2CCOCC2)C(c2ccc(F)cc2)/C1=C(/O)c1ccc(S(=O)(=O)N2CCOCC2)cc1
