Task: Answer the multiple choice question.
Query: Which compound exhibits a 1.004\% 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, or d without using any other words.
Options:
a) Cn1c(=O)c2c(ncn2CCO)n(C)c1=O
b) CCCN(CC1CC1)C(=O)CSc1ncnc2sccc12
c) O=[n+]1c2c(n([O-])c3c1CCCC3)CCCCC2
d) O=C(O)c1cccc(-n2cccc2/C=C2/NC(=O)N(Cc3ccccc3F)C2=O)c1
Answer: c. O=[n+]1c2c(n([O-])c3c1CCCC3)CCCCC2
