Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.433\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] CNC(=O)CC1C(=O)N(C)C(=S)N1NC(=O)c1ccc(Cl)cc1
[b] NC(=O)N1c2ccccc2C=Cc2ccccc21
[c] N#CCCN1CCN(Cc2cc(-c3ccccc3)ccc2O)CC1
[d] O=C(COC(=O)c1ccco1)c1ccc2ccccc2c1
Answer: c. N#CCCN1CCN(Cc2cc(-c3ccccc3)ccc2O)CC1
