Task: Answer the MCQ question.
Query: Which drug has a 7.775\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. CNC(=O)/C(C#N)=C/c1c(N(Cc2ccccc2)Cc2ccccc2)nc2c(C)cccn2c1=O
b. CCn1c(SCC(=O)Nc2cc(NC(C)=O)ccc2OC)nnc1-c1ccccn1
Answer: a. CNC(=O)/C(C#N)=C/c1c(N(Cc2ccccc2)Cc2ccccc2)nc2c(C)cccn2c1=O
