Right choice is (a) Brass and bronze

For explanation: Investment casting method is also known as the lost wax method. This method is used to make brass and bronze statues of religious images, jewelry, and dentistry. The molten metal is poured into an already made mold cavity by melting the mold pattern in the mold itself.
