still on syllabus
i had da sme prob but....
now i tink its 4 sure C
more dan one reason
one : yes wen its in series resistance increases thus current decreases
two: HAVE U EVER READ ON A BATTERY SUPPLY OF CURRENT? NO, CUSE CURRENT ISN'T DEPENDANT ON DA CELL buh upon voltage and resistance across da cell....its a variable value nt like voltage fixed due to the cell supply  8)
so its C

I ASKED THE SAME ELECTRICAL ENGINEER AGAIN AND HE SAID WE SHOULD CHOOSE C I WAS WRONG IN THE BEGINNING AND THE JUSTIFICATION IS THAT THE CURRENT IN THE PARALLEL CIRCUIT DEPEND ON THE TOTAL VOLTAGE AND TOTAL RESISTANCE SO CHANGING ONE WILL OBVIOUSLY CHANGE THE CURRENT AND AS THE RESISTANCE INCREASED THE CURRENT WILL BE DECREASED WHICH HOPE EXPLAINED ABOVE

cuz in parralel the resistance is less it is given by the equation R=1\r1+1\r2 then invert the answer

Because the lamps are not in parallel anymore. M is left in series, when N is removed. And as you know, effective resistance is lesser in parallel, than when in series!
