A glass tube of uniform internal radius(...

A glass tube of uniform internal radius(r) has a valve separating the two identical ends. Intially, the valve is in a tightly closed position. End 1 has a hemispherical soap bubble or radius r. End 2 has sub-hemispherical soap bubble as shown in figure. Just after opening the valve,

A

air from end 1 flows towards end 2. no change in the volume of the soap bubble

B

air from end 1 flows towards end 2. volume of the soap bubble at end 1 decreases

C

no change occurs

D

air from end 2 flows towards end 1. volume of the soap bubble at end 1 increases
