Brut [27]

Answer:

Although the question is incomplete, missing options are

  • In 1997, they reduced their water consumption.
  • In 1996, they planted more trees to curb water pollution.
  • In 1994, they used only bottled water for drinking purpose.
  • In 1995, they complained about foul odor and taste in water.

Correct option: <em><u>In 1996, they planted more trees to curb water pollution. </u></em>

Explanation:

Among given options, a clear trend of nitrate level can be seen. <u>Initially, the nitrate level increased in water in first two years (1994 and 1995) and then it decreased significantly</u>.

From the conditions given in the question, the most probable answer is B the plantation effect (<u>phytoremediation</u>). During phytoremediation, <u>plants take up nutrients including nitrate</u> from the water via roots. This nitrogen is then used for the growth and development of plant body mass (e.g. amino acids). As more plants were growing in later years, higher reduction of nitrate was seen. Resultantly, in 1997, the concentration of nitrate was dropped to 7.3 mg/L.

The other options are not correct due to following reasons.

A. There is no information on water consumption in the question

C. There is no information on people's behavior on drinking water lifestyle.

D. Nitrate in the water cannot be smelled or tasted.

<span>Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together. (Domesticated) animals are known as breeds, normally bred by a professional breeder, while domesticated plants are known as (varieties), cultigens, or cultivars. Two purebred animals of different breeds produce a (crossbreed). Flowers, vegetables and fruit-trees may be bred by amateurs and commercial or non-commercial professionals: major crops are usually the provenance of the professionals. </span>

In the given features all the provided options are present in the vascular plants and absent in the non-vascular plants but flowers and fruits are the option which is found in some vascular plants especially in the plants of the angiosperm families and are absent in non-vascular plants also.

Thus, Flowers and fruits are the correct answer.
