Which function is typically used to obtain the leftmost five characters of a string?

• A. Mid
• B. Left
• C. Right
• D. Substring

Answer: (B)

To get the leftmost five characters, you use a function that extracts from the start of the string. The Left function does exactly that: it takes the string and the number of characters to take from the left, returning the initial portion. For example, Left('Database', 5) yields 'Datab'. If the string is shorter than five characters, it returns the whole string. This direct leftward extraction is why it’s the best fit for obtaining the leftmost characters, unlike functions that start from a specific position or from the end.
