Task: Answer the MCQ question.
Question: Which drug has a 7.891\% 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. O=C(NCCc1c[nH]c2ccccc12)C1CCN(S(=O)(=O)c2ccc(F)cc2)CC1
b. COCCCNC(=O)C1=CCN(S(=O)(=O)c2ccc(OC)cc2)CC1
c. O=c1[nH]cnc2c1c(-c1ccccc1)cn2-c1cccc(Cl)c1
Answer: c. O=c1[nH]cnc2c1c(-c1ccccc1)cn2-c1cccc(Cl)c1
