Practice question

Correct option is C, Simple columnar epithelium. In Tissue-I, the accurate description is Simple columnar epithelium, and that is what you should commit to memory. Keep the definition tight and the role clear — location matters here: Simple columnar epithelium is the structure or site that matches the description. Then Simple columnar epithelium is the answer you can defend. Check yourself by covering the options and writing the answer first, then matching the letter — that builds confidence. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Simple columnar epithelium. Remember that physiology questions reward precise language: name the process, the location, and the outcome, then match that to the option text.
