If the price of tangerines increases, the price of oranges also rises because

a- if the supply of tangerines decreased, then the supply of oranges also must decrease.

b- buyers' incomes must have decreased and oranges are an inferior good.

c- consumers consider the two goods substitutes and demand for oranges increases.

d- consumers consider the two goods complements and so sellers decreased the supply of oranges.

Please explain it clearly and avoid handwriting

Thank you
