Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 0.550\% 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] CCC(=O)N1N=C(c2c(-c3ccccc3)c3cc(Cl)ccc3[nH]c2=O)CC1c1ccco1
[b] O=C(CSc1nc(-c2ccc(Cl)cc2)cs1)Nc1cccc([N+](=O)[O-])c1
[c] COc1cccc2c1OCC(CN1CCN(Cc3ccccc3)C(CCO)C1)=C2
[d] CN(C(=O)Oc1ccc([N+](=O)[O-])cc1)c1ccccc1
Answer: a. CCC(=O)N1N=C(c2c(-c3ccccc3)c3cc(Cl)ccc3[nH]c2=O)CC1c1ccco1
