Task: Answer the multiple-choice question.
Query: Which drug has a 1.694% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] COCCNC(=O)C(=O)c1c(-c2ccccc2)[nH]c2ccccc12
[b] CCn1cc(C2C(C(=O)Nc3cc(C)ccn3)=C(C)NC3=C2C(=O)CC(C)(C)C3)c(C)n1
[c] O=C(NCc1cn2ccccc2n1)c1ccco1
[d] CCc1ccc(C)c(OC(=O)c2cncc(Br)c2)c1
Answer: a. COCCNC(=O)C(=O)c1c(-c2ccccc2)[nH]c2ccccc12
