In 1995 Richard, a well known critic of the patent system, testified in patent of his hearings that, to test the system, a colleague of his had managed to win a patent for one of Kirchoff's laws, an observation about electric current first made in 1845 and now included in virtually every text book of elementary physics.

a) laws, an observation about electric current first made in 1845 and
b) laws, which was an observation about electric current first made in 1845 and it is
c) laws, namely, it was an observation about electric current first made in 1845 and
d) laws, an observation about electric current first made in 1845, it is

Picking 'E' becuase 'is' is required to end the undeline portion.

leaves B, D and E

B is out because 'which was' can not modify laws.

'An observation' seems to modify laws, which is not singular.

That seems to modify the patent accurately. So -> 'E'

OA??

b) laws, which was an observation about electric current first made in 1845 and it is -- it can refer to observation or electric current..incorrect
c) laws, namely, it was an observation about electric current first made in 1845 and -- laws and it..Also, namely is awkward..incorrect
d) laws, an observation about electric current first made in 1845, it is -- it can refer to observation or electric current..incorrect

Is not , first made in 1845 modifies the complete "an observation about electric current" or it only modifies the electiric current.

What is general rules regarding the , and modifier. Getting a clarity on this would be really helful.
