Task: Answer the multiple choice question.
Question: Which compound exhibits a 5.633\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) CN1CCc2nc(SCc3ccc(C(C)(C)C)cc3)c(C#N)cc2C1
b) Cc1nc(SCC(=O)NCC2CCCO2)[nH]c(=O)c1C
c) CC(NC(=O)C1c2ccccc2Oc2ccccc21)C1CCCO1
d) O=C(CSc1ncccn1)NN=C1CCCCCC1
Answer: d. O=C(CSc1ncccn1)NN=C1CCCCCC1
