Prices for bicycles can run — Tk. 2,00,00.

✅ কেন সঠিক: ‘As high as’ is the fixed expression for an upper limit: prices can run as high as a certain amount.

❌ অন্য অপশন: ‘So high as’ is used mainly after a negative; ‘as high to’ and ‘as high for’ are not correct forms.

💡 মনে রাখুন: as + adjective + as: as high as, as much as, as many as. (The amount ‘Tk. 2,00,00’ is printed this way in the question.)
