Now before taking the inverse tangent of both sides, recall that

where

is any integer. This means that when taking the inverse tangent of

, instead of just

, we would end up with

So after doing so in the equation above, we're left with

As

can be any integer, including negative integers, we can simply write
We are given
The current exchange rate is 2 guilders for every 3 florins
so,
2 guilders = 3 florins
now, we can find for 1 guilders
so, we get

now, we can multiply both sides by 17

now, we can simplify it

so, option-A........Answer
