Two identical, isolated conducting spheres, A and B, carry initial charges of \(+4Q\) and \(-2Q\), respectively. The spheres are brought into brief physical contact and then separated. Which of the following correctly gives the final charge on each sphere and the direction of net electron transfer while they were in contact?

Choice	Final Charge on Each Sphere	Direction of Net Electron Transfer
A	\(+2Q\)	From Sphere B to Sphere A
B	\(+Q\)	From Sphere B to Sphere A
C	\(+Q\)	From Sphere A to Sphere B
D	\(+2Q\)	From Sphere A to Sphere B
