Task: Answer the MCQ question.
Question: Which drug exhibits a 4.766\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) O=C(C1CCCCN1S(=O)(=O)c1ccccc1[N+](=O)[O-])N1CCOCC1
b) C/C=C(/C)C(=O)O[C@@H]1c2cc3c(c4c2[C@@]2(CO4)C(=O)C(OC)=C(OC)C=C2C[C@@H](C)[C@H]1C)OCO3
Answer: b. C/C=C(/C)C(=O)O[C@@H]1c2cc3c(c4c2[C@@]2(CO4)C(=O)C(OC)=C(OC)C=C2C[C@@H](C)[C@H]1C)OCO3
