I'm not sure, but I think substr(1, 5) and substring(0, 5) would give us 'Sales'.

I agree with Gail, because substr starts at the specified index and extracts the specified number of characters, while substring extracts characters between two specified indices.

But substr() includes the starting index, while substring() does not. So, A) and B) are correct.

Definitely B) and D). Anything else would be 'Sales'-ing yourself short!

Ah, the good old 'substr' vs 'substring' debate. I'm going with B) and D) - they just roll off the tongue, you know?

Hmm, I think B) and D) are the way to go. Who needs 'substr' when you've got 'substring'? It's like having two spoons when one will do!

The correct answers are B) and D). 'substr' and 'substring' both return the characters from the specified indices, but 'substr' takes the length as the second argument, while 'substring' takes the end index.
