C Correct answer
Explanation

Trapa (water chestnut) is a floating-leaf hydrophyte - its roots are fixed in mud at the bottom, while leaves float on the water surface. Ceratophyllum, Najas, and Utricularia are submerged hydrophytes that float freely or are completely underwater without roots anchored in mud.
