rules question: spell duration: detect magic

[Nimor Starseeker]

Detect magic has a duration of concentration, up to 1 min/Level, so does that mean the following a or b:

A) My LV2 character can concentrate for up to 2 minutes?

OR

B) My Lv2 character can concentrate for several hours and when ceases to concentrate, the spell lasts for 2 minutes?

I think it is B, because here:

it says that some spells last for a short time after you cease concentrating.

I think case B will have specific description given, eg:Mislead.

For Detect Magic, the max duration is 1 min/level, and it ends when you cease concentration (though you can just cast this cantrip again and again)

Option A is correct: It lasts until you either stop concentrating - or - it hits the maximum duration, whichever happens to come first.

Option B would be presented as 'concentration + 1 minute/level' (see Wall of Fire as an example of this).
