After performing the left join operation as shown in the code snippet above, which statement is true about the resulting merged$\_$data DataFrame?

Group of answer choices

All rows from stock$\_$data will be included, and rows from sentiment$\_$data without a matching Stock$\_$Ticker in stock$\_$data will have NaN for the Sentiment$\_$Score.

The resulting DataFrame will contain all rows from both stock$\_$data and sentiment$\_$data, regardless of a match.

Only the rows with matching Stock$\_$Ticker and Date in both stock$\_$data and sentiment$\_$data will be included.

Rows from stock$\_$data with no matching row in sentiment$\_$data will be excluded from merged$\_$data.
