Problem statement: Answer the MCQ question.
Query: Which drug has a 2.534\% 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] Br.COc1ccc(/C(O)=C/Sc2nnc(Cc3ccccc3)o2)cc1
[b] CCOc1ccc(S(=O)(=O)N(CC(=O)NC2CCCCC2C)Cc2ccco2)cc1
[c] OCCNc1ncnc2c1c(-c1ccccc1)c(-c1ccccc1)n2Cc1ccco1
Answer: a. Br.COc1ccc(/C(O)=C/Sc2nnc(Cc3ccccc3)o2)cc1
