Task: Answer the multiple choice question.
Question: Which drug exhibits a 6.183\% 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, or c without using any other words.
Options:
a. O=C(CC1NCCNC1=O)Nc1ccc2c(c1)OCCO2
b. O=C(CCCN1C(=O)c2cccc3cccc(c23)C1=O)NCc1cccs1
c. O=C1CCC(=O)N1c1cccc(OS(=O)(=O)c2ccccc2)c1
Answer: a. O=C(CC1NCCNC1=O)Nc1ccc2c(c1)OCCO2
