Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -4.427\% 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] CCCCOP(=O)(c1ccc(N(C)C)cc1)C(O)c1ccc(C(C)C)cc1
[b] N=c1c2c3c(sc2ncn1CCN1CCOCC1)CCCCC3
[c] CCOC(=O)N(C)c1ccc(C(O)(C(F)(F)F)C(F)(F)F)cc1
[d] CCOc1cc(C)c(C(C)C)cc1S(=O)(=O)N1CCN(C)CC1
Answer: b. N=c1c2c3c(sc2ncn1CCN1CCOCC1)CCCCC3
