Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 19.000% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: O=C(COC(=O)c1cccnc1Cl)Nc1nnc(-c2ccccc2)o1
b: O=c1oc2ccccc2c(O)c1Cc1cc(Cl)c2cccnc2c1O
c: CN(C)c1ccc(C2N(c3ccc(F)cc3)C(=O)C3CCCN32)cc1
d: O=c1[nH]n(-c2cccc(Cl)c2)c2ncccc12
e: O=C(Nc1cccc(-c2cn3ccccc3n2)c1)c1cccc(Cl)c1
Answer: a. O=C(COC(=O)c1cccnc1Cl)Nc1nnc(-c2ccccc2)o1
