Second option: B and C

Step-by-step explanation:

A is the product of 4x and -2x: A=(4x)(-2x)→A=-8x^2 (x^2)

B is the product of 4x and 3: B=(4x)(3)→B=12x (x^1)

C is the product of 1 and -2x: C=(1)(-2x)→C=-2x (x^1)

D is the product of 1 and 3: D=(1)(3)→D=3 (constant)

Then, the like terms are B and C
