C
Commutative property of addition
a + b = b + a
Commutative property of multiplication
a . b = b . a
Distributive property of multiplication over addition.
xa + xb = x (a + b)
So,
Using Distributive property of multiplication over addition
5a(4b)+5a(6c) = 5a (4b + 6c)
Using Commutative property of multiplication
5a (4b + 6c) = (4b + 6c) 5a
