Task: Answer the multiple-choice question.
Query: Which compound exhibits a 0.529\% 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. CCc1nnc(NC(=O)CSc2ccc(-c3ccc(-n4cccn4)cc3)nn2)s1
b. CCOC(=O)c1c(CSC(=N)N)n(-c2ccccc2)c2cc(Br)c(OC(C)=O)cc12
c. COc1ccc(-n2c(=O)n(Cc3ccccc3)c(=O)c3[nH]cnc32)cc1
d. CC(=O)C(Sc1nnnn1-c1ccccc1)C(C)=O
e. COc1ccc(CC(=O)NNS(=O)(=O)c2ccc3ccccc3c2)cc1OC
Answer: c. COc1ccc(-n2c(=O)n(Cc3ccccc3)c(=O)c3[nH]cnc32)cc1
