Answer:
B
Step-by-step explanation:
If a figure is reflected over the y-axis, its y-coordinates remain the same and x-coordinates become opposite. This means that the reflection over the y-axis has the rule
[tex](x,y)\rightarrow (-x,y)[/tex]
When a figure is translated (lowered) 6 units down, then the rule of this translation is
[tex](x,y)\rightarrow (x,y-6)[/tex]
Hence, correct option is B
[tex](x,y)\rightarrow (-x,y)[/tex]
and
[tex](x,y)\rightarrow (x,y-6)[/tex]
