Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 4.463\% 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] CC(=O)NCc1ccc(S(=O)(=O)N/N=C/c2ccc(N(C)C)cc2)cc1
[b] CN1C(C(=O)NCc2cccc(C(F)(F)F)c2)CC2Cn3c(nc4ccccc43)C21
[c] COc1ccc(C(=O)Nc2ccc3c(c2)C(=O)N(C)C3=O)cc1OC
[d] CCN(CC)CC#CC(C)(C)OC(C)=O
Answer: d. CCN(CC)CC#CC(C)(C)OC(C)=O
