Task: Answer the MCQ question.
Question: Which drug has a -3.361\% 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, or d without using any other words.
Options:
a: CCOc1cc(/C=N/NC(=O)c2cc(C)[nH]n2)ccc1OC(=O)c1ccc([N+](=O)[O-])cc1
b: CC1=C(CO)C(=O)OC([C@@H](C)C2CC[C@H]3C4C[C@H]5O[C@]56[C@@H](O)C=CC(=O)[C@]6(C)C4CC[C@]23C)C1
c: CCOCCn1c(SC)nc2c1c(=O)[nH]c(=O)n2C
d: CCCCN1C(=O)C(O)=C(C(C)=O)C1c1ccc(OC)cc1OC
Answer: b. CC1=C(CO)C(=O)OC([C@@H](C)C2CC[C@H]3C4C[C@H]5O[C@]56[C@@H](O)C=CC(=O)[C@]6(C)C4CC[C@]23C)C1
