Task: Answer the multiple-choice question.
Question: Which drug has a 8.379\% 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 additional words.
Options:
a: COc1cc(/C=N/NC(=O)Cc2nnc(NC(=O)c3ccccc3)s2)ccc1O
b: CCCCN(Cc1ccccc1)C(=O)C1CCN(Cc2sccc2C)CC1.O=C(O)C(=O)O
c: O=C(NCCCN1CCCC1=O)c1cc2ccccc2o1
d: CC(CO)N1CCS(=O)(=O)CC1
Answer: c. O=C(NCCCN1CCCC1=O)c1cc2ccccc2o1
