Answer:
Option B, [tex](48x^{8}y^{5})[/tex]
Step-by-step explanation:
Step 1: Simplify the exponent
[tex](12x^{2}y^{3})(2x^{3}y)^{2}[/tex]
[tex](12x^{2}y^{3})(2^{2}x^{3*2}y^{1*2})[/tex]
[tex](12x^{2}y^{3})(4x^{6}y^{2})[/tex]
Step 2: Simply the expression
[tex](12x^{2}y^{3}*4x^{6}y^{2})[/tex]
[tex](48x^{2+6}y^{3+2})[/tex]
[tex](48x^{8}y^{5})[/tex]
Answer: Option B, [tex](48x^{8}y^{5})[/tex]
