### Solution:

Concept- To find the LCM of fractions first we need to find the LCM of the numerators and HCF of denominators.
Then we need to divide LCM of numerators by HCF of denominators.
LCM of numerators 5, 15, 25 is 75
HCF of denominators 16, 24, 8 is 8, because 8 is the highest common factor for these three numbers.
LCM of fractions = LCM of numerators divided by HCF of denominators.
LCM of given numerators = HCF of given denominators 16, 24, 8 = 8
LCM of given fractions = So now to get LCM of the fractions simple divide LCM of numerators with HCF of denominators and we get .
Hence, the correct answer is option 4.
