Task: Answer the multiple-choice question.
Question: Which drug has a 6.649\% 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, or c without using any additional words.
Options:
a Cc1ccc(N(C)C(=O)C2CCN(S(=O)(=O)c3ccc4c(c3)oc(=O)n4C)CC2)cc1
b Cc1cc(C)c(S(=O)(=O)N2CCN=C2c2ccccc2)c(C)c1
c CCOC(=O)C(C(=O)OCC)C(C)(C)/C(C)=N\Nc1ccc([N+](=O)[O-])cc1[N+](=O)[O-]
Answer: b. Cc1cc(C)c(S(=O)(=O)N2CCN=C2c2ccccc2)c(C)c1
