B. is correct. Let's look at the others...
A-- we know salt deposits are not alive.
C-- True, salt deposits are not alive, but they do not respond to stimuli... this is a characteristic of living things.
D-- Salt deposits are not alive and do not maintain homeostasis.

Introduction
The growth and development of plants under varied environmental conditions determine agricultural production. The growth, development, and senescence of plant’s organs can influence crop production by modulating photosynthesis, nutrient remobilization efficiency, and harvest index (Paltridge et al., 1984; Jing et al., 2005; Iqbal et al., 2012). Phytohormones have been shown to increase growth and yield of plants. The phytohormone ethylene controls growth and senescence of plants (Reid, 1995; Lutts et al., 1996; Thompson et al., 1998; Pierik et al., 2006; Masood et al., 2012; Nazar et al., 2014). Ethylene is regarded as a multifunctional phytohormone that regulates both growth, and senescence. It promotes or inhibits growth and senescence processes depending on its concentration, timing of application, and the plant cell

Answer:
Respiration is a person's breathing and the movement of air into and out of the lungs.
Explanation:
The respiratory system provides oxygen to body tissues for cellular respiration, removes the waste product carbon dioxide.
The controlis the plant with just water. The independent variable is the plants. The dependaent is the amout of salt in the water.
The indepedent is the trees. The dependent is the greenhouse or no greenhouse.
