Problem statement: Answer the multiple choice question.
Query: Which drug has a 6.138\% human ether-à-go-go related gene (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 CCOC(=O)c1cc2sccc2n1Cc1ccc(C#N)cc1
b O=C1CS/C(=C/C(=O)c2ccccc2)N1
c NC(=O)/C=C\C(=O)Nc1cccc(C(F)(F)F)c1
d CCOC(=O)c1ccc(NC(=O)N(CC)CC)cc1
e Cc1ccc(-c2cc(C(=O)NCc3ccco3)no2)cc1
Answer: a. CCOC(=O)c1cc2sccc2n1Cc1ccc(C#N)cc1
