I don't know the official answer, but I also think that answer is C, as two numbers will be 40 and 10, and their HCF is 10

Having a HCF means that this number can be factored out from the two numbers summed to get 50. Thus, it would be something as \(c(x+y) = 50\)- Thus, 50 must be divisible by the HCF c. Then, the highest number among the choices that is a factor of 50 is 10. Answer C
