I would go with the A version.
Also have you tried using fading to make it more realistic.

Events unit enters region Your_Region_Name

Condition

Actions

Unit Pause entering unit

Fade in/out/in and out over desired_amount_of_sec using desired_effect

wait desired_amount_of_sec /2

Unit move instantly to House region

Camera pan to position of entering unit for owner of entering unit

Unit unpause entering unit
Just an suggestion try it, cause it is more realistic than just poping on the other side of the map in a sec.
Now step-by-step:
First you need an region and then when an unit enters the region you pause the entering unit and make the screen fade(try difrent fade shapes to see which suits your purpose) set the time of fading to an example 6 seconds then in the next action put wait for 3 seconds so that when you move and pan the camera the screen will be faded. You could use the fade out and in which is i think the best solution. The fading action is located in the Cinematic action group, that is Cinematic - Fade(not sure if it is exactly like this but it is in the Cinematic group 100%)
