Check all that apply vs. Check all that applies

[Kking]

I'm working on a website and I have a few check boxes with different options.

Should it read

"I would consider myself (Check all that apply)"
# Business Traveler
# Leisure Traveler
# Meeting Planner
# Corporate Travel Planner
# Travel Agent

OR

"I would consider myself (Check all that applies)"
# Business Traveler
# Leisure Traveler
# Meeting Planner
# Corporate Travel Planner
# Travel Agent

thanks for your help!

"All" is plural, so it should read, "Check all that apply."
