PLEASE HELP! Lina and Josh each made a factor tree to find the prime factorization of 126.
Lana Josh

  9   7
Which statement explains the accuracy of the students’ work?
a)Lina’s solution is correct because it expresses 126 as a product of prime factors.
b)Josh’s solution is correct because the factor tree of every even number must begin with 2 and its factor pair.
c)Both solutions are correct because they both express 126 as a product of factors.
d)Neither solution is correct because the factor tree should have begun with 6 and 21.
