Which one is a mangrove plant?

  1. Potamogeton

  2. Sagittaria

  3. Rhizophora

  4. Populus


Correct Option: C

Rhizophore is a

  1. Stem branch

  2. Root

  3. Reproduction organ

  4. Intermediate between A and B


Correct Option: D

Halophiles can comfortably live in

  1. Dead sea

  2. Dal lake

  3. Arabian sea

  4. Godavari


Correct Option: A
Explanation:

Halophiles are organisms that thrive in high salt concentrations. They are also called as salt-loving microorganisms. They are found in hypersaline environments like in arid, coastal, deep‐sea, underground salt mines. They can comfortably live in evaporation ponds or salt lakes such as Great Salt Lake, Owens Lake or Dead Sea. 

Thus, the correct answer is 'Dead Sea.'
