Task: Answer the multiple-choice question.
Query: Which drug exhibits a -1.983% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] Cc1cc(N(C)C)c(C#N)c(NCc2ccccc2)n1
[b] Cc1nn(-c2ccccc2)c(C)c1/C=N/NC(=O)c1cc(-c2cccs2)[nH]n1
[c] COc1cc(/C=C/c2cccc[n+]2C)ccc1OCC(=O)Nc1ccccc1C.[I-]
[d] Cc1oc(-c2cccc(Cl)c2)nc1CN1CCCC(C(=O)NC(C)c2ccc3c(c2)OCCO3)C1
Answer: a. Cc1cc(N(C)C)c(C#N)c(NCc2ccccc2)n1
