Problem statement: Answer the multiple choice question.
Query: Which drug has a -2.719\% 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] COc1ccc(-c2ccnc3nc(Sc4ncc(C(F)(F)F)cc4Cl)nn23)cc1
[b] COC(=O)C[C@H]1c2cc(C(F)(F)F)ccc2S(=O)(=O)N1C(C)(C)C
[c] O=C(COc1ccc(Br)cc1)N(Cc1cccs1)C1CCS(=O)(=O)C1
[d] COc1ccc(-c2ccc(/C=C3/C(=N)N4C(C)=CSC4=NC3=O)o2)c([N+](=O)[O-])c1
Answer: a. COc1ccc(-c2ccnc3nc(Sc4ncc(C(F)(F)F)cc4Cl)nn23)cc1
