Is this for bends in general or a specific bend?
You have tightening bends, bends that open up, off camber bends etc.
We have all gone in a bit hot to a bend and have had to ease off but this as Trevor has stated above will unsettle a vehicle's balance.
Adjusting speed through braking or acceleration is ok if you have the traction and traction is dependant on tyre and road surface plus the variables such as water mud temperature leaves etc.
It's one thing flinging it around a track where corner attributes do not vary that wildly and tyre degradation is more predictable but going into a blind bend hot to find a road covered in mud normally results in a number of things happening at once and how these are handled will normally dictate if you make it through the bend...
Throttle lift off, braking, feathering the steering are all options but all can compromise traction be it drive or steering. Modern cars have ASC ABS and some are blessed with Quattro. All of these contribute to an ignorance factor where the car looks after the driver and all you will notice regarding a driving indiscretion is a few flashes of an icon on a dashboard.
Drive with wild abandon in a Caterham or good old TVR and where ambition overtakes ability it normally results in a hole in a hedge.
If you are trying to emulate a racing driver then you do all your braking before the corner entry accelerating through and out of the bend my short answer would be B
Last bit of advice would be if you are looking to improve the commute home qualifying time practice it on a track - yes Shell Grip track surfaces provide higher levels of traction but the key secret is balance.
