Task: Answer the multiple-choice question.
Query: Which drug exhibits a -40.303% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) CCOC(=O)c1cn2nc(OP(=S)(OCC)OCC)cc2nc1C
b) O=C(O)c1cccc(Nc2ccncc2[N+](=O)[O-])c1
c) O=C(NCCCN1CCOCC1)/C(=C/c1cccs1)NC(=O)c1ccccc1
Answer: a. CCOC(=O)c1cn2nc(OP(=S)(OCC)OCC)cc2nc1C
