Correct Answer: Option D
Explanation

When one atom supplies both electrons in forming a two-electron bond, it is known as a dative covalent or coordinate bond. If two atoms contribute one electron each, it is known as a simple covalent bond. when ammonia and hydrogen ions bond together to form ammonium ion, the type of bond formed is a dative/coordinate covalent bond, because ammonia supplied both electrons with hydrogen contributing nothing.
