Task: Answer the multiple choice question.
Question: Which compound exhibits a 4.572\% 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, c, d, or e without using any other words.
Options:
a O=C(NCCN1CCOCC1)C(Sc1ccccc1)c1ccccc1
b O=C(Cc1ccccc1)NS(=O)(=O)c1ccc(N=NN2CCOCC2)cc1
c O=P(c1ccccc1)(c1ccccc1)C(O)c1ccccn1
d COCCOC(=O)c1c(C)oc2ccc(NS(=O)(=O)c3cccs3)cc12
e Cc1cccc(N(CC(=O)N2CCCC2)S(=O)(=O)c2ccccc2)c1C
Answer: d. COCCOC(=O)c1c(C)oc2ccc(NS(=O)(=O)c3cccs3)cc12
