In the 19th century where did the European scholars discover images of the Buddha and Bodhisattvas that were seemingly influenced by Greek models?

In the northwest regions, such as Taxila and Peshawar

The correct answer is Option 4 - In the northwest regions, such as Taxila and Peshawar

It will be useful to recall that when nineteenth-century European scholars first saw some of the sculptures of gods and goddesses, they could not understand what these were about. Sometimes, they were horrified by what seemed to them grotesque figures, with multiple arms and heads or with combinations of human and animal forms.

These early scholars tried to make sense of what appeared to be strange images by comparing them with sculpture with which they were familiar, that from ancient Greece. While they often found early Indian sculpture inferior to the works of Greek artists, they were very excited when they discovered images of the Buddha and Bodhisattas that were evidently based on Greek models. These were, more often than not, found in the northwest, in cities such as Taxila and Peshawar, where Indo-Greek rulers had established kingdoms in the second century BCE. As these images were closest to the Greek statues these scholars were familiar with, they were considered to be the best examples of early Indian art
