Task: Answer the multiple choice question.
Question: Which compound exhibits a 12.766\% 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: CCN(CC)S(=O)(=O)c1ccc2oc(SCC(=O)NC3CC3)nc2c1
b: COc1cccc2cc(C(=O)NCCC3=CCCCC3)c(=O)oc12
c: O=C(Oc1ccccc1)n1c(=S)oc2ccccc21
d: Cc1nn(Cc2ccccc2)c2ncccc12
Answer: c. O=C(Oc1ccccc1)n1c(=S)oc2ccccc21
