By factorizing algebraic expression 36ab - 48bc, answer must be
Answer: C
Look for the common factors of the coefficients and the variables.
\[ 36ab - 48bc = 6b(6a - 8c) \]
Checking: \( 6b \times 6a = 36ab \) and \( 6b \times 8c = 48bc \).
The variable \( b \) appears in both terms and comes out; \( a \) and \( c \) do not. A fuller factorisation is \( 12b(3a - 4c) \), but among the options only \( 6b(6a - 8c) \) expands back correctly.
