Are spaces between arrows and activation bars considered errors?

[iwle]

With regards to Q25 of the Mock Paper, I observe that there are three errors (as circled in red).

Reason being, the arrows do not touch the activation bar.

However the answer is (B), i.e., there are no errors; why so?

Thanks!

@iwle Will let one of your classmates answer this first.

I circled the exact 3 errors when I was doing the paper but it turns out that the answer says that there are no errors. This is indeed puzzling.

I believe what matters more is the position of the arrows rather than whether there is a small space between the activation bar and the arrow. As long as it is clear what the arrow is doing (dotted or not, where does it start, end), it should be ok. Note the text book notation errors does not specifically point out that this is an error.
