Task: Answer the multiple-choice question.
Query: Which drug has a 4.742\% 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: CNC(=O)CSc1nnnn1-c1cc(C)ccc1C
b: COC(=O)c1cc(NS(=O)(=O)c2ccc(N3CCCCC3)c([N+](=O)[O-])c2)cc(C(=O)OC)c1
c: O=C(Cn1nc(-c2ccccc2Cl)ccc1=O)Nc1ccccc1-c1ccccc1
Answer: a. CNC(=O)CSc1nnnn1-c1cc(C)ccc1C
