There are four metal rods of lengths 102 cm, 136 cm, 153 cm and 289 cm each. They are all cut into parts having equal maximum length. Select the option showing the total number of parts of all the rods.

First, find the HCF of the rod lengths (102, 136, 153, 289) to get the maximum length of equal parts, which is 17 cm. Then divide each rod's length by 17 and sum the number of parts to get the total.
