Problem statement: Answer the multiple choice question.
Query: Which drug has a -4.159\% 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. O=C(N/N=C1\CCCc2ccccc21)C(O)c1ccccc1
b. COc1cc(/C=C2/NC(=O)N(Cc3ccccc3F)C2=O)cc(OC)c1OC
c. Cc1cccc(C(=O)NNS(=O)(=O)c2ccc(F)cc2)c1
d. Cc1c(NC(=S)NC(=O)c2cccc(Br)c2)c(=O)n(-c2ccccc2)n1C
e. CCOC(=O)C1(C)NC(c2ccco2)C2C(=O)N(c3ccc(C)cc3)C(=O)C21
Answer: a. O=C(N/N=C1\CCCc2ccccc21)C(O)c1ccccc1
