Task: Answer the MCQ question.
Question: Which drug has a 20.781\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] CCN1CCN(c2cn[nH]c(=O)c2Cl)CC1
[b] COc1cc(/C=N/NS(=O)(=O)c2ccc(C)c([N+](=O)[O-])c2)ccc1O
[c] O=S(=O)(c1ccc(NCc2ccccc2)cc1)N1CCOCC1
[d] O=c1cc(-c2ccc(Cl)cc2)[nH]c2ccccc12
[e] CCN(CCn1cccn1)C(=O)CC1C(=O)NCCN1Cc1ccc(F)cc1
Answer: c. O=S(=O)(c1ccc(NCc2ccccc2)cc1)N1CCOCC1
