The nematodes or roundworms constitute the phylum Nematoda and have a pseudocoelom and complete digestive system. The partial, fluid-filled cavity inside the body of some invertebrates. Cnidarians have two different body plans. Both body plans have radial symmetry. A polyp, such as a hydra, sea anemone, or coral, is shaped something like a vase. Platyhelminthes, a group of soft-bodied, usually much flattened invertebrates and have cavity only one opening to the outside which, in most cnidarians, is surrounded by tentacles for capturing prey. But Porifera does not have a gastrovascular cavity as it does not have specialized tissues and phyla with a true coelom and digestive system. The protostomes include the phyla Mollusca, Annelida, and Arthropoda but not porifera. 

Biotechnology is the use of living systems and organisms to develop or make products, or "any technological application that uses biological systems, living organisms or derivatives thereof, to make or modify products or processes for specific use. For thousands of years, humankind has used biotechnology in agriculture, food production, and medicine. 

Application of biotechnology occurs in agriculture, biomedicine and environmental field.

Biotechnology is the use of biological processes, organisms, or systems to manufacture products intended to improve the quality of human life. The earliest biotechnologists were farmers who developed improved species of plants and animals by cross pollination or cross breeding. 

Citric acid is a weak organic acid with the formula -CHO. It is a natural preservative or conservative which occurs naturally in citrus fruits and is also used to add an acidic or sour taste to foods and drinks. Griseofulvin is an orally administered antifungal drug. It is used both in animals and humans, to treat fungal infections of the skin and nails. Whereas cephalosporins are a group of broad spectrum, semi-synthetic beta-lactam antibiotics derived from the mould Cephalosporium. Streptomycin is an antibiotic (antimycobacterial) drug, the first of a class of drugs called as aminoglycosides to be discovered,

The correct option is C

Modern biotechnology is based on the the methods of genetic engineering.  It is a technique which involves the introduction of foreign DNA carrying the desired gene of interest into the host organism & thus change the phenotype of the host organism.
