Which of the following lines of code will return the metadata description?
A . There is no way to return the metadata description programmatically.

Answer: C

Explanation:

To retrieve the metadata description of a feature table created using the Feature Store Client (referred here as fs), the correct method involves calling get_table on the fs client with the table name as an argument, followed by accessing the description attribute of the returned object. The code snippet fs.get_table("new_table").description correctly achieves this by fetching the table object for "new_table" and then accessing its description attribute, where the metadata is stored. The other options do not correctly focus on retrieving the metadata description.
