Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 14.425\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: Cc1csc(=O)n1CC(=O)OCC(=O)c1c(N)n(C)c(=O)n(C)c1=O
b: O=C(CSc1ccsc1[N+](=O)[O-])NCCc1ccc(Cl)cc1
c: CNC(=O)CSc1nc2ccccc2c(=O)n1-c1cc(OC)ccc1OC
d: O=C(O)c1cncc(C#Cc2ccccc2)c1
e: Cn1c(CCc2ccc(N)cc2)nc2ccccc21
Answer: d. O=C(O)c1cncc(C#Cc2ccccc2)c1
