Holo-whole and zoic means animals so animal that eats their food completely in the form of a liquid or solid and process it inside the body. The food particle is ingested and then enzymes act on it to digest it. It includes five steps ingestion, digestion, absorption, assimilation and excretion and most of the animals practice this type of nutrition including humans.

Living systems in general maintain a high intracellular concentration of potassium and low intracellular concentration of sodium. Living systems operate sodium potassium pump for this purpose which actively throws out sodium from the cytoplasm and transports potassium ions from extracellular environment to inside the cytoplasm.

Epidemiological studies revels that low serum Selenium levels are associated with increased risk of  cardio-vascular diseases, liver necrosis, muscular dystrophy, pancreatic fibrosis, reproductive disorders and various cancers.
Selenium, along with vitamin E, prevents the development of hepatic necrosis and muscular dystrophy.
The good sources of Selenium are organ meat ( liver, kidney) and sea food.

Sodium is an essential element for many marine plants and organisms, playing a key role in osmotic balance and cellular function in saline environments.

Lead, platinum, and iodine are not considered essential nutrients for the normal growth and development of plants, unlike the others listed which are micronutrients or macronutrients.

Holozoic nutrition is the process of taking in solid or liquid organic food, which is then digested and absorbed by the organism.

Selenium is a vital trace element that acts as an antioxidant; its deficiency is linked to conditions like liver necrosis and muscular dystrophy in various animals.

Microphagial nutrition involves feeding on very small particles, which is characteristic of Paramecium using its cilia to sweep food into its oral groove.

None of the options is correct. However, in some cases toxic level of Nickel is approached well above the concentration of $1$mg/g as that of macronutrients.
