Hi
I have a problem in organic chemistry which I need help with.

What reagent(s) would be appropriate to accomplish the conversion shown?

The options are:
A. HCl
B. HNO3
C. H2SO4
D. HBr
E. K2Cr2O7 + H2SO4

for the first one it is the dehydration of alcohol
so you can use sulfuric acid

I think both the pictures are same
