Task: Answer the multiple-choice question.
Question: Which drug exhibits a -9.509\% 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 other words.
Options:
a CCN(CC)c1ccc(N=Cc2c(O)n(-c3ccccc3)c(=O)[nH]c2=O)cc1
b CN(C)c1ccc(-c2nc3ccccc3n2C)cc1
c O=C(CCN1CCN(c2ccccc2)CC1)NNC(=O)c1cccc2ccccc12
d CSC1=C(C#N)C(CC(C)C)C(C(C)=O)=C(C)N1
Answer: a. CCN(CC)c1ccc(N=Cc2c(O)n(-c3ccccc3)c(=O)[nH]c2=O)cc1
