Explanation:

Step1: Recall group 17 electron - configuration

Elements in group 17 have 7 valence electrons.

Step2: Analyze Lewis - dot structures

A Lewis - dot structure represents valence electrons as dots around the symbol of the element. We need to find a structure with 7 dots around the symbol 'X'.

Step3: Evaluate options

Option A has 2 dots, option B has 4 dots, option C has 6 dots, and option D has 7 dots.

Answer:

D.
