Answer: c) and b) are correct.
The brain is encased in a protective bony or cartilaginous housing in craniates.
The anterior end of the nerve cord is elaborated to form a brain in craniates.
Explanation: The craniates include the chordata with well-defined heads. This includes mammals, reptiles and fishes. So we can discard the other answers. Because most craniates have functional jaws, and the adults do not lose their chordate characteristics. The last one does not apply as a specific feature because the tunicate have neural crest but are not recognized as craniata.

Answer:
Spoilage microbes produce acid
Explanation: 
When food becomes spoiled or is unprotected, bacteria will invade the food. These types of bacteria are called spoilage bacteria. The bacteria will multiply by consuming the nutrients from the food and grows very rapidly. In certain conditions, the invading bacteria will produce acids that protects them and creates a barrier for other microbes. This acid is what gives spoiled food a sour taste.
