Task: Answer the multiple choice question.
Question: Which compound has a 3.554\% 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(C)(C)NC(=O)NC(=O)CN1CCN(Cc2ccccc2)CC1
b) O=C(Nc1ccccc1)N(C1=NCCCCS1)c1cccc2ccccc12
c) CCc1ccc2[nH]c(=O)c(C3C(C#N)=C(N)Oc4c3ccc3cccnc43)cc2c1
d) Cc1cc(C)cc(NC(=O)COC(=O)c2n[nH]c3ccccc23)c1
Answer: c. CCc1ccc2[nH]c(=O)c(C3C(C#N)=C(N)Oc4c3ccc3cccnc43)cc2c1
