Explanations:The question asks about the location of the establishment of APCTT, which stands for the All India Institute of Speech and Hearing (AIISH). This institution is a significant center for research and education in the fields of speech and hearing. It was established in Bangalore, the capital city of Karnataka, India.
Understanding the context of the question requires knowledge of the acronym APCTT and its connection to Bangalore. Bangalore, also known as Bengaluru, is a major city in Karnataka and is renowned for its contributions to education, technology, and research. The All India Institute of Speech and Hearing (AIISH) is one of the premier institutions in the country dedicated to the study and treatment of speech and hearing disorders.
It is important to note that while New Delhi, Mumbai, and Chennai are all significant cities in India, they are not the locations of APCTT. New Delhi is the capital of India and hosts many national institutions, Mumbai is a major commercial and financial hub, and Chennai is known for its industrial and technological advancements. However, APCTT is specifically located in Bangalore, which is a major educational and research center in Karnataka.
Therefore, the correct answer is that APCTT was established in Bangalore. This question tests the student's knowledge of the location of important institutions in India and their ability to correctly identify the city associated with a specific acronym.
