Task: Answer the multiple choice question.
Query: Which drug exhibits a 5.982\% human ether-à-go-go related gene (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 other words.
Options:
a. CC(NC(=O)c1ccccc1F)c1nnc(SCC(=O)NC2CCCC2)n1C
b. CCN(CC)CCN1C(=O)C(O)=C(C(=O)c2cc3ccccc3o2)C1c1cccnc1
c. CN(C)S(=O)(=O)c1cccc(NC(=S)N/N=C/C(=O)c2ccccc2)c1
d. CC(C)(C)c1nc(N2CCN(C(=O)c3ccco3)CC2)c2nnn(Cc3ccccc3)c2n1
Answer: b. CCN(CC)CCN1C(=O)C(O)=C(C(=O)c2cc3ccccc3o2)C1c1cccnc1
