Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.707\% 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 O=C1CCOc2cc(OCc3ccccc3)ccc21
b COC(=O)/C=C1\SC(N2CCOCC2)=C(c2ccc(OC)cc2)C1=O
c CC(C)C(NC(=O)c1ccc(C(C)(C)C)cc1)C(=O)O
d Cc1cccn2c(=O)c3cc(C(=O)NCCN4CCOCC4)c(=N)n(Cc4cccnc4)c3nc12
Answer: c. CC(C)C(NC(=O)c1ccc(C(C)(C)C)cc1)C(=O)O
