this is the location (whrer /which) i choose to set up the new company

which definitely

which because it is an object

which
is the correct answer

عندى طريقة ميسرة للتفرقة بين where / which

لاحظ
This is the school where I go

where do you go?

This is the school which I go to

which school do you go?

طريقة مش بطاله لو طبقناها على المثال ده

which location do you choose to set up your company?

ممكن تبقى where بس فى الحالة دى

where will you set up your company

عايزك تتاكد من تصريف الفعل choose / chose / have chosen

والله اعلم
