Task: Answer the multiple choice question.
Query: Which compound has a 16.742\% 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] COC(=O)c1ccc(Cl)c(NC(C)=O)c1
[b] Cc1ccc(N2C(=O)NC(=O)/C(=C/c3cnc(-c4ccccc4)nc3)C2=O)cc1C
[c] CCn1c2c(c3cc(C(=O)O)ccc31)CCCC2=O
[d] Cc1ccccc1NC(=O)c1ccc(-c2ccc(Cl)cc2Cl)o1
Answer: c. CCn1c2c(c3cc(C(=O)O)ccc31)CCCC2=O
