In a relational database, a "Not applicable" condition can be represented in different ways depending on the specific database system and the context. Here are the options you provided:

a. NULL: This is a common way to represent a "Not applicable" or "unknown" condition in a database. NULL means that a data value does not exist in the database.

b. NA: This is not a standard way to represent "Not applicable" in a database, but it could be used depending on the specific system or context. It's more commonly used in data analysis languages like R to represent missing or not applicable data.

c. 0: This is typically not used to represent "Not applicable" because it is an actual value. Using 0 could lead to confusion or incorrect calculations.

d. Blank Space: This could be used to represent "Not applicable", but it could also lead to confusion because it might look like the data was accidentally left out.

So, the most standard and widely accepted way to represent "Not applicable" in a relational database is NULL. However, the best choice can depend on the specific database system and the context.
