Task: Answer the multiple-choice question.
Question: Which drug has a 4.491\% 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] C=CCc1cccc(CNc2c(C)n(C)n(-c3ccccc3)c2=O)c1O
[b] O=C(Cc1cccc(F)c1F)NC1CCCN(Cc2ccc(Cl)cc2)C1
[c] O=C(O)C1C2CCC(C2)C1C(=O)NCc1ccco1
[d] CCOC(=O)c1cc(C)n(CCc2cnc[nH]2)c1C
Answer: d. CCOC(=O)c1cc(C)n(CCc2cnc[nH]2)c1C
