The apparent weight can be calculated by:
Apparent weight = Real weight - Force due to acceleration/upward motion
The elevator is moving upward with a speed of 3 m/s and slowing down at 2 m/s^2. So, the acceleration due to upward motion is -2 m/s^2 (negative because it's in the opposite direction to the upward motion). 
Force due to acceleration/upward motion = mass x acceleration = 490/9.81 x 2 = 100 N (taking g as 9.81 m/s^2)
So, Apparent weight = 490 - 100 = 390 N. 
Therefore, the correct choice is A) 390 N.
