Which one of the following important trade centres of ancient India was on the trade route connecting Kalyana with Vengi ?

The correct answer is Tagara. Standard MCQ answer keys and preparatory materials identify Tagara (ancient Ter) as the important inland trade centre located on the route linking Kalyana in the Deccan with Vengi on the eastern coast, serving as a key hub for east–west overland trade in antiquity. Tagara functioned as an entrepôt where goods from the Deccan and western regions were consolidated and forwarded toward eastern ports, distinguishing it from Tamralipti (a maritime port in Bengal) and Tripuri or Sripura (located on other corridors). Competitive-exam compilations therefore list Tagara as the correct choice for the Kalyana–Vengi trade route question.
