The temperature in a casserole rises from 20°F to 85°F. Express these two temperatures in °R, °K, and °C.

a) 20°F = 527.67°R, 266.48°K, -6.67°C; 85°F = 545.67°R, 302.04°K, 29.44°C
b) 20°F = 527.67°R, 266.48°K, -6.67°C; 85°F = 545.67°R, 302.04°K, 29.44°C
c) 20°F = 526.67°R, 265.48°K, -7.67°C; 85°F = 544.67°R, 301.04°K, 28.44°C
d) 20°F = 525.67°R, 264.48°K, -8.67°C; 85°F = 543.67°R, 300.04°K, 27.44°C
