A factory makes a product that has a manufacturing process consisting of tasks A, ... , K that must be completed in an order that obeys a set of precedence requirements. The following table reports the performance time in minutes/unit and the preceding task(s) for tasks A, ... , K.

Task	Performance Time	Preceding Tasks
A	3	NA
B	1	NA
C	1	A
D	3	A, B
E	1	B
F	2	C
G	5	F
H	6	D, E
I	10	H
J	1	E
K	10	G, I, K

The precedence network is: The line will operate for 480 minutes per shift. The desired shift output is at least 22 units. Please match the following:

The configuration Station 1 (BDE); Station 2 (ACF); Station 3 (HIJ); Station 4 (GK) The configuration Station 1 (ABD); Station 2 (CEF); Station 3 (GHI); Station 4 (JK) The configuration Station 1 (ACF); Station 2 (BDE); Station 3 (HJ); Station 4 (GIK)		1)	Is not valid because at least one precedence requirement is violated.
		2)	Ensures meeting the desired output.
		3)	Is not valid because it does not meet the desired output
