Problem statement: Answer the MCQ question.
Question: Which drug exhibits a -1.946\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) CCCCn1c(O)c(C(C)=NCCN2CCCCC2)c(=O)[nH]c1=O
b) CCC(=NCc1cccnc1)c1c(O)n(-c2ccccc2C)c(=O)[nH]c1=O
c) O=C(CCCN1C(=O)/C(=C/c2ccccc2Cl)SC1=S)NNC(=O)c1ccccc1Cl
Answer: a. CCCCn1c(O)c(C(C)=NCCN2CCCCC2)c(=O)[nH]c1=O
