Task: Answer the multiple choice question.
Question: Which drug exhibits a 1.845\% 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 other words.
Options:
a) CC(=O)OCC1(C)CN(c2ccccc2)N(C(C)=O)C1=O
b) CC1CCCCC12NC(=O)N(CC(=O)c1ccc(Cl)s1)C2=O
c) CC(NC(=O)c1cc(-c2cccs2)on1)c1ccccc1
d) CCCCCCCCc1nnc(N)s1
Answer: a. CC(=O)OCC1(C)CN(c2ccccc2)N(C(C)=O)C1=O
