B) It allows Spark to optimize the query plan before execution but does not adapt during runtime.
C) It automatically distributes tasks across nodes in the clusters and does not perform runtime adjustments to the query plan.
D) It enables the adjustment of the query plan during runtime, handling skewed data, optimizing join strategies, and improving overall query performance.

2. A data scientist has identified that some records in the user profile table contain null values in any of the fields, and such records should be removed from the dataset before processing. The schema includes fields like user_id, username, date_of_birth, created_ts, etc.
The schema of the user profile table looks like this:

Which block of Spark code can be used to achieve this requirement?
Options:

A) filtered_df = users_raw_df.na.drop(how='any')
B) filtered_df = users_raw_df.na.drop(thresh=0)
C) filtered_df = users_raw_df.na.drop(how='all', thresh=None)
D) filtered_df = users_raw_df.na.drop(how='all')
