a)
Interpretation:
The names of solutes that separates with poly (dimethylsiloxane)-coated open tubular column has to be given.
Concept introduction:
Open tubular columns:
The open tubular columns are made of silica (in fused form) and is coated with Polyimide for the support and to protect from atmospheric moisture. The most common type of open tubular column is wall coated column and the less common type is porous layer column. The columns are coiled in such way that they fit within a particular temperature controlled column oven.
Advantages and disadvantages of open tubular columns:
Open tubular columns provides higher resolution but short time analysis and show greater sensitivity when compared to packed columns. These columns have less capacity of the sample.

Interpretation:
The names of solutes that separates with poly (ethyleneglycol)-coated open tubular column has to be given.
