Yeah, and why isn't Tonga on this quiz? How dare a quiz of just a few countries miss out the country I'm interested in, don't they know just how much the world must revolve around my part of the world...?
It depends on how you consider "urban area" and "city proper". Ecatepec (as well as every other Mexico City suburb) is a municipality, with a Municipal President (mayor) and everything else. Since each municipal government is based on a city proper (that normally shares the same name), Ecatepec counts as a city proper. However, it's normally considered into the Mexico City metro area when listing the largest cities in Mexico, making it quite obscure for many people (even in Mexico).
I assumed you would take the borders of the region of Brussels (Brussels-Capital Region, +1000000 inhabitants) into account, as is standard, rather than the borders of the city of Brussels, an outdated remnant of Belgian history. Both can be argued to be correct, so I won't press the issue.
To quote the wikipedia article on Brussels, just to show the ambiguous nature of the issue:
"Brussels [...], officially the Brussels-Capital Region[...] is the capital and largest city of Belgium and the de facto capital of the European Union (EU)."
"The city has a population of 1.2 million and a metropolitan area with a population of over 1.8 million, both of them the largest in Belgium."
Funny that this was just featured. I just spent some time yesterday making a quiz about Second Largest Cities. Literally just posted it. http://www.jetpunk.com/user-quizzes/66830/countries-by-second-biggest-city
I take it that Salonika is no longer a valid name for Thessaloniki. Oh well, was just being a bit lazy and didn't want to type out Thessaloniki in full!
Citywise I consider Birmingham second after London. Although there are two cities in London considering the British city definition (place with a catthedral) - City of London and City of Westminster. London divided by two is still bigger as Birmingham I guess. Very confusing this stuff. Furthermore, I think it depends on how you count if Greater Manchester or the West Midlands are the bigger urban area.
I couldn't write Thessaloniki correctly.
Osaka didn't came into my mind, same as Alexandria.

No, that is too cruel -- a hint: perhaps two extremes of Europe.
I suspect that both were early capital cities in their effective countries (economic regions).
