Task: Answer the multiple choice question.
Query: Which drug exhibits a 1.455% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) O=C(COc1cccnc1[N+](=O)[O-])NCCc1ccccc1
b) Nc1nonc1-n1nnc(C(=O)N/N=C/c2ccncc2)c1-c1ccccc1
c) C[C@H](NC(=O)c1nc[nH]c1C(=O)NCCCCC[NH3+])C(=O)OC(C)(C)C.[Cl-]
Answer: a. O=C(COc1cccnc1[N+](=O)[O-])NCCc1ccccc1
