Answer:
I don't have as much time for reading as I would like to.
Explanation:
The sentence should read: "I don't have as much time for reading as I would like to."
Here's why:
"As" is used to introduce a comparison between two things. In this case, you're comparing the amount of time you have available (don't have as much) with your ideal situation (would like to).
The other options don't fit grammatically or logically in this sentence.
