This is the exact copy of the note per the instructions for item number 2.b. The way I read it is I need to choose 2.a. Am I correct or reading it too deep?
NOTE: Do not select this reason for filing if the card was mailed to you at the address you provided, and it was never returned as undeliverable to USCIS. To determine if your card was returned to USCIS, check your case status online at www.uscis.gov/casestatus. You can also call the USCIS National Customer Service Center at 1-800-375-5283. For TTY (deaf or hard of hearing) call: 1-800-767-1833. If the card was not returned as undeliverable to USCIS, then you must file Form I-90 using reason “2.a.” (My previous card has been lost, stolen, or destroyed).
