Task: Answer the multiple choice question.
Query: Which drug has a 5.758\% 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 additional words.
Options:
[a] O=C(OCC(=O)N1CCCC1)c1cccc(Br)c1
[b] O=C(NCCN1CCN(c2ccccc2)CC1)Nc1ccccc1Cl
[c] COc1ccc(C)c(-n2c(N)cc(=O)n(Cc3ccccc3)c2=O)c1
[d] CCOCCn1c(CN(Cc2ccccc2)Cc2ccccc2)nc2c1c(=O)[nH]c(=O)n2C
Answer: a. O=C(OCC(=O)N1CCCC1)c1cccc(Br)c1
