Task: Answer the MCQ question.
Question: Which drug exhibits a -0.191\% 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) O=C(C(=O)N1CCN(C(=O)c2ccco2)CC1)c1c[nH]c2ccccc12
b) O=C(O)c1ccc2c(c1)C(=O)/C(=C\c1ccco1)C2=O
c) CC#CC(=O)NCC1(N(C)Cc2ccccc2)Cc2ccccc2C1
Answer: b. O=C(O)c1ccc2c(c1)C(=O)/C(=C\c1ccco1)C2=O
