Task: Answer the multiple choice question.
Question: Which compound has a 20.378\% 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 additional words.
Options:
a: Cc1ccc(N(CC2CO2)S(=O)(=O)c2ccc(C)cc2)cc1
b: O=c1oc(-c2ccc(Br)o2)nc2ccccc12
c: CCC(=NCCc1c[nH]c2ccccc12)c1c(O)n(-c2ccc(C)cc2)c(=O)[nH]c1=O
Answer: c. CCC(=NCCc1c[nH]c2ccccc12)c1c(O)n(-c2ccc(C)cc2)c(=O)[nH]c1=O
