Answer #1

In this question we have 2 main statement

01. First one tells us that HPLC grades solvent are costlier and can be used without purifying it

Yes this statement is correct the HPLC grade solvents are highly pure and that makes them way more costlier than normal solvents

02. Statement 2 is degassing of solvent prior to use is important

This statement is also correct because small bubbles formed in the solvent can interfare with our results if they enter in the column

So degassing them. Insures avoiding this error

So due to this the correct option is

both of the statements are correct

I hope this helps. If you have any query or want more detailed explanation, feel free to ask in the comments section below.
