The variable satsifaction_ratings has been assigned to a Pandas Data Frame that contains customer satisfaction ratings for a small business. This DataFrame is indexed by a column labelled Date, and contains columns labelled Average Rating (giving the average customer rating to the nearest integer) and Supervisor (containing the name of the employee supervising the business over that period (as a string)). The first date in the index column is 21-09-24. Using this information, identify which of the following calls would not result in an error being raised. a. satsifaction_ratings['21-09-24'] b. satsifaction_ratings['Supervisor']['21-09-24'][0] Oc. satsifaction ratings.loc[0] ○ d. satsifaction_ratings['Date'] e. satsifaction_ratings.head(4)[0] satsifaction ratings.loc['Average Rating'] Clear my choice

Remember, the main difference between a correlated subquery and uncorrelated subquery is that, in a correlated subquery, the inner query is dependent upon the outer query, while, with an uncorrelated query, the inner query does not depend upon the outer query. Instead, it runs just once. You should NOT use union, minus, or intersect in this query. The outer query will use the PRODUCT table and the inner query will use the VENDOR table [hint: you should have 9 records of output].
