Task: Answer the multiple-choice question.
Query: Which drug has a 4.231\% 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, or c without using any additional words.
Options:
[a] O=C(NC1CCCCC1)N1CCc2[nH]c3ccccc3c2C1
[b] CCOC(=O)N1CCN(C(=O)c2nn(-c3ccc(C)cc3)c(=O)c3c2c2ccccc2n3C)CC1
[c] O=c1[nH]cnc2c1cnn2Cc1ccccc1
Answer: a. O=C(NC1CCCCC1)N1CCc2[nH]c3ccccc3c2C1
