Best answer
The correct choice is (c) 1600^oC

To explain: White Portland cement is similar to ordinary and grey Portland cement in most aspects. This differs from other types of Portland cement due to their white appearance, which is a result of low Fe2O3 content. As opposed to the normal operating at 1450^oC, white Portland cement requires sintering at 1600^oC.
