Task: Answer the multiple-choice question.
Query: Which drug has a 16.636\% 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 additional words.
Options:
a: CCN(C(=O)COC(=O)c1cc(-c2ccccc2)nc2c1c(C)nn2-c1ccccc1)C1CCS(=O)(=O)C1
b: Cc1nn(C)cc1/C=N/NC(=O)CSc1ccccn1
c: NC(=O)COC(=O)CC1CC2CCC1C2
d: O=C(O)c1cc2c(s1)CCCC2
Answer: d. O=C(O)c1cc2c(s1)CCCC2
