Detailed Explanation:

Halophytes are plants specially adapted to survive in high-salt environments, tolerating concentrations up to 1M NaCl. Common examples include mangroves and salt marsh vegetation.

Xerophytes thrive in dry/desert conditions, Mesophytes in moderate environments, and Glycophytes are salt-sensitive plants that cannot tolerate saline conditions.

Therefore, salt-loving plants are Halophytes, making Option 3 the correct answer.
