Task: Answer the multiple choice question.
Question: Which compound exhibits a 20.281\% 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) CC1CCCN(C2=C(NS(=O)(=O)c3ccc(Br)cc3)C(=O)c3ccccc3C2=O)C1
b) CC(=O)NC1=NN(C(C)=O)C(c2cccs2)S1
c) CCCP(=O)(CC(=O)N(CC)CC)c1ccccc1
d) O=C(O)c1cccc(Oc2ncnc3sc4c(c23)CCCC4)c1
Answer: b. CC(=O)NC1=NN(C(C)=O)C(c2cccs2)S1
