The correct answer should be B because bulb B and C are in parallel connection,and current flows equally in parallel connection.So the brightness of bulb A will remain same but the brightness of bulb B will decrease,as the current which was flowing only to bulb B will now flow to both bulb B and bulb C.i have reported error for this question
