Task: Answer the MCQ question.
Question: Which drug has a 1.948\% 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: Cl.O=C(COc1ccccc1)N1CCN(CC(O)COc2ccccc2)CC1
b: CCCS(=O)(=O)c1c(S(=O)(=O)CCC)c2c(N)cccn2c1C(=O)c1ccc(OC)cc1
c: O=C(COc1cccc2ccccc12)NNC(=O)C1CCCO1
Answer: c. O=C(COc1cccc2ccccc12)NNC(=O)C1CCCO1
