Task: Answer the multiple choice question.
Query: Which compound exhibits a 22.548\% 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 additional words.
Options:
a CCC1(c2ccc(F)cc2)NC(=O)N(CC(=O)NC2CC2)C1=O
b Cn1c(CC(=O)Nc2ccccc2)c(Sc2ccccc2)c2ccccc21
c O=c1c2cc3c(cc2[nH]c(=S)n1C1CCN(Cc2ccccc2)CC1)OCO3
d O=C(CC1CCCC1)Nc1nnc(C2CC2)s1
Answer: a. CCC1(c2ccc(F)cc2)NC(=O)N(CC(=O)NC2CC2)C1=O
