Explanation:

First statement is correct. Vesara Style: It emerged during early medieval period. It is a hybrid style that borrowed from the northern and southern styles. So, it is a mixture of both Nagara and Dravida styles of temple architecture. Temples built in the Deccan under the later Chalukyas of Kalyani and Hoysalas are considered examples of this style.
Second statement is correct. The most characteristic feature of Hoyasalas temples is that they grow extremely complex with so many projecting angles emerging from the previously straightforward square temple so that the plan of these temples starts looking like a star. As the plan looks like a star, it is known as stellate plan.
Third statement is correct. They are usually made out of soapstone. The intricately carved banded plinths, a distinguishing characteristic of the Hoysala temples, comprise a series of horizontal courses that run as rectangular strips with narrow recesses between them.
