Task: Answer the multiple choice question.
Question: Which drug has a 5.914\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a C=C(C)C(C)(C#CCN1CCCC1)OC(C)=O
b Cc1cc2ncc(Cl)nc2cc1C
c COC(=O)Cn1cnc2c1c(=O)n(C)c(=O)n2C
d O=C(NCCn1ccc2ccccc21)c1ccc2c(c1)OCO2
e CCc1ccc(NC(=O)NCCN2CCc3ccccc3C2)cc1
Answer: c. COC(=O)Cn1cnc2c1c(=O)n(C)c(=O)n2C
