Madadia is served by 6 subway lines - A, E, I, O, U and Z.

When it snows, morning service on line E is delayed.

When it rains or snows, service on the lines A, U and Z is delayed both morning and afternoon.

When the temperature drops below 20 C, afternoon service is cancelled on either line A or line O, but not both.

When the temperature rises above 40 C, afternoon service is cancelled on either line I or line Z, but not both.

When service on line A is delayed or cancelled, service on line I is also delayed.

When service on line Z is delayed or cancelled, service on line E is also delayed.
On February 10, it snows all day with the temperature at 18C. On how many lines service will be delayed or cancelled, including both morning and afternoon?

quite straightforward.

I disagree. Line O could be cancelled and not conflict with statement 3. Statement 3 says that A or O will be 'cancelled', but not both. Line A could be 'delayed' from statement 2 and line o could be 'cancelled' and that wouldn't conflict any statements. So I think there are two possible solutions.
