Task: Answer the multiple-choice question.
Question: Which drug has a 18.634\% 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) CC(=NCCN1CCOCC1)c1c(O)n(-c2ccccc2C)c(=O)[nH]c1=O
b) CC(=O)C(/C=N/c1cc(-c2ccc(C)cc2)nn1-c1ccccc1)=C(\C)O
c) COc1ccc(C(c2c(O)nc[nH]c2=O)c2c(O)nc[nH]c2=O)cc1
d) COc1cccc(CN2CCN(C(=O)c3cccc4ccccc34)CC2)c1OC.O=C(O)C(=O)O
Answer: c. COc1ccc(C(c2c(O)nc[nH]c2=O)c2c(O)nc[nH]c2=O)cc1
