The correct option is C halophytes
Halophytes are plants which are found growing on salt marshes, commonly called as the mangrove plants. They form specialised breathing roots which grow upwards, negatively geotropic and helps in respiration.
The embryo formed in these plants come out of the seed and the fruit while it is still attached to the plant
A xerophyte is found growing in regions where there is very less water available. A mesophyte needs moderate amount of water and a psammophyte is found in deserts. All these have roots which are positively geotropic and hydrotropic.
