Task: Answer the multiple-choice question.
Query: Which drug exhibits a 9.592% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a NS(=O)(=O)c1cc(C(=O)OCC(=O)NNC(=O)c2ccccc2)ccc1Cl
b Cc1ccc(NC(=O)c2oc3ccc(S(=O)(=O)N4CCOCC4)cc3c2C)cc1C
c CCOC(=O)CSC1=NC(=O)/C(=C\c2ccc(OC(C)=O)cc2)S1
d CCOC(=O)c1cnc(SCCN2CCOCC2)nc1N
Answer: d. CCOC(=O)c1cnc(SCCN2CCOCC2)nc1N
