See: Option Class.
An option series separates calls and puts. We know, not very enlightened. Maybe, one day, puts and calls can choose their own series. But we haven't reached that point yet.
For now, a particular series includes either all the calls or all the puts for a single underlying asset, with the same strike price and the same expiration. So calls for NFLX with a strike price at $360 and a July expiration would count as one series; meanwhile, puts for NFLX with a strike price at $360 and a July expiration would represent another series.

Finance allah shmoop what is the intrinsic value of an
option All right this is brandi She owns a twelve
dollars strike price call option toe buy a share of
my fifteen minutes are up dot com a retirement home
chain for reality tv stars who recently gained self awareness
Well the stock is trading for fifteen bucks a share
of this moment Her strike price is twelve so the
intrinsic value of that option is fifteen minutes twelve or
three bucks that is it is three dollars in the
money and if brandy converted it into a share this
moment and then immediately sold the stock for fifteen dollars
in cash well she'd make three bucks But there's a
catch per call option doesn't expire for five weeks so
that three dollars in the money is actually worth more
than three dollars because she has data or time yet
to exercise and convert or just sell the option itself
So it's worth mohr because well a stock might go
up from fifteen dollars in overtime Stocks go up so
in the next five weeks well couldn't go up a
dime twenty cents twenty five cents and make that three
Dollars worth three ten three twenty three Twenty five Sure
sure it could happen So yeah that's The difference between
actual value and intrinsic value You get seita kickers in
there making the option's worth more than just converting them
into stock and selling them right there And yeah it
looks like our one and a half minutes are up
