Which ofthe following statements is correct?

$1$ point

Keras is a high$-$level API that facilitates fast development and quick prototyping of deep learning models.

PyTorch normally runs on top of a low$-$level library such as TensorFlow.

Keras and PyTorch are both supported by Google and are being actively used at Google for both research and production needs.

Among TensorFlow, PyTorch, and Keras, Keras is the most popular library and is mostly used in production of deep learning models.

TensorFlow is the cousin of the Torch framework, which is in Lua, and supports machine learning algorithms running on GPUs in particular.
