Task: Answer the multiple-choice question.
Query: Which drug has a 2.625\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] Nc1nc(N)nc(-c2ccccn2)n1
[b] CCN(CC(=O)Nc1c(F)cccc1F)C(=O)c1ccc(-c2ccc(C(C)=O)cc2)o1
[c] OCC1(Cc2ccc(F)cc2)CCCN(CCc2ccccc2)C1
[d] O=C(O)CN1C(=O)CC(c2ccccc2)CC1=O
[e] COc1cc(NS(=O)(=O)c2ccc(NC(=O)/C=C/c3ccc([N+](=O)[O-])cc3)cc2)ncn1
Answer: b. CCN(CC(=O)Nc1c(F)cccc1F)C(=O)c1ccc(-c2ccc(C(C)=O)cc2)o1
