`q_(1), q_(2), q_(3) and q_(4)` are point charges located at points as shown in thte figure and S is a spherical Gaussian surface of radius R. Which of the following is true according to the Gauss.s law

A

`oint(vec(E_(1))+vec(E_(2))+vec(E_(3))).dvec(A)=(q_(1)+q_(2)+q_(3))/(epsilon_(0))`

B

`oint(vec(E_(1))+vec(E_(2))+vec(E_(3))+vec(E_(4)))dvec(A)=(q_(1)+q_(2)+q_(3))/(epsilon_(0))`

C

`oint(vec(E_(1))+vec(E_(2))+vec(E_(3))).dvec(A)=((q_(1)+q_(2)+q_(3)+q_(4)))/(epsilon_(0))`

D

`oint(vec(E_(1))+vec(E_(2))+vec(E_(3))+vec(E_(4))).dvecA=((q_(1)+q_(2)+q_(3)+q_(4)))/(epsilon_(0))`
