A positive point charge Q is placed (on the axis of disc) at a distance of 4 R . Above the centre of a disc of radius R as shown in situation I. the magnitude of electric flux through the disc is `(phi)`. Now a hemis pherical shell of radius R is placed over the disc. such that it forms a closed surface as shown in situation II. The flux through the curved suface in situation II taking direction of area vector along outward normal as positive is
A. Zero
B. `phi`
C. `-phi`
D. `2phi`
