When transportation costs are added to production costs, it becomes unprofitable to ship some products over a large distance. This is particularly true of products that Multiple Choice require locally sourced raw materials. have a high value-to-weight ratio. have a low value-to-weight ratio. can be produced only in one region.

The reason is that the transportation cost is connected with the weight of the product whereas the profit of the profit will diminish if the value to weight is low which means that the profit generated is very low which will be paid off to transport the product. So the option C is correct.

Option A is not connected with transportation cost which turns the profitable products into unprofitable products due to its high cost.

Option B is opposite of option C hence both are incorrect.

Option D is incorrect because if the product is only produced in one region then it will be the only firm offering that product which means it can price its product geographically to adjust the transportation cost. Hence it is also not connected with the transportation cost which turns the profitable products into unprofitable products due to its high cost.
