Concept:This item tests the correct spelling of a commonly misspelled English word.
Explanation:The word "itinerary" means a schedule or planned route for a journey.
The correct spelling is i-t-i-n-e-r-a-r-y.
It contains the letters "iner" after the second "i" and ends with "-ary".
Option A, "itinery", omits one "i" and misplaces the letters.
Option C, "itenery", incorrectly uses an "e" in place of the second "i".
Option D, "itinarary", wrongly repeats the "ar" segment.
Only option B, "itinerary", matches the exact dictionary spelling used in standard English.
Answer:Option B. itinerary
