Task: Answer the MCQ question.
Question: Which drug has a -4.008\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] O=C1CC(c2ccccc2)CC(O)=C1C=NCCCN1CCOCC1
[b] O=C(N/N=C\c1ccc([N+](=O)[O-])s1)C1COc2ccccc2O1
[c] Cc1cc(=O)[nH]c(SCc2cccc(F)c2)n1
[d] O=C(O)CSc1nc2ccccc2s1
Answer: a. O=C1CC(c2ccccc2)CC(O)=C1C=NCCCN1CCOCC1
