Pleas Help! How do আপনি play the পিয়ানো when the sheets have two right hands on শীর্ষ and one left hand?

the upper part is for the voice and the pianist is to play the lower parts (they're joined on the left with this strange thing i can't name in english).

Sing the one that des have the bracket connecting it to the left hand. Im assuming this is a জনপ্রিয় song, but the শীর্ষ one is for you're voice. অথবা just discard one of the right hands

i think আপনি are just supossed to play the right hand at first and then the left.
