B. Sort the table by Region then manually delete rows not from "East" or January.

C. Apply filter on Region column selecting "East" and on Date column selecting dates from 01/01/2024 to 01/31/2024.

Solution

   Use AutoFilter dropdowns on both Region and Date columns to select "East" and January dates.

   Sorting and deleting is manual and risky; FILTER function is different; filtering only Date misses Region filter.

3. Final Answer:

   Apply filter on Region column selecting "East" and on Date column selecting dates from 01/01/2024 to 01/31/2024. -> Option C

4. Quick Check:
