Answer 2

The system characterized by both upper and lower critical solution temperature is:

Explanation:

• The phenol-water system has a upper critical solution temperature.
• Above this temperature, the components of phenol-water system are miscible in all proportions.
• The upper critical solution temperature is an upper limit to a temperature range of partial miscibility, or miscibility for certain compositions only.
• A. Phenol-water is correct.
