Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 10.380\% 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=C1NC(=O)C(=Cc2ccc(-c3ccc(F)cc3O)o2)C(=O)N1
b: O=C(NCC(c1ccco1)N1CCc2ccccc21)c1ccccc1F
c: O=C(OCC(=O)N(CCc1ccccc1)Cc1ccccc1)c1ccccc1O
d: CN1CCN(Cc2nc3ccccc3n2C)CC1CCO
Answer: d. CN1CCN(Cc2nc3ccccc3n2C)CC1CCO
