Can you patent the "electric bulbs"? Shouldn't it be the singular "electric bulb"?

Hi,
I have taken the following approach to solve this question. Please correct me if I am wrong.
First, let us understand the actual intent of the sentence. The intended meaning of the sentence is:-
In 1876, Alexander Graham Bell invented the telephone and then three years after that Edison patented the electric bulb.
First Event:- Alexander Graham Bell invented the telephone in 1876
Second Event:- Three years after 1876, Edison patented the electric bulb.
Two events occurred in the past, the earlier event should take Past Perfect and the later event should take Simple Past.
Let us review the options:-
Option A:- In 1876, three years before Edison patented the electric bulb,
The double past structure is proper i.e earlier event(the invention of the telephone by Alexander Graham Bell) is denoted with past perfect and later event(Patenting of electric bulb by Edison) is denoted by simple past. So, the intended meaning is also coming out. As of now, we can keep this option.
Option B:-In 1876, three years before Edison had patented the electric bulb,
The double past structure is improper .i.e later event(Patenting of the electric bulb by Edison) is also denoted by past perfect. So the correct sequence of events is not coming out.
So we can eliminate this option.
Option C:- Three years before Edison patented the electric bulb in 1876,
The intended meaning of these sentences is wrong. This somehow indicates that Edison has patented the electric bulb in 1876, which is not the case. The telephone was invented in 1876 and the electric bulb was patented 3 years after that.
So we can eliminate this option.
Option D:- Before Edison patented the electric bulb in a duration of three years in 1876,
There are two things wrong with this statement.
First of all, this statement indicates that Edison has patented the electric bulb in 1876, which is not the case. The telephone was invented in 1876 and the electric bulb was patented three years after that.(Same error as Option C)
Secondly, because of the usage of "duration of three years", this statement also indicates that the process of patenting the electric bulb took three years. We are not sure about this, so we cannot say that.
We can safely eliminate this option.
Option E:- In 1876, three years before Edison had obtained the patent rights for the electric bulb,
This has the same error as option B.The double past structure is improper i.e. later event is also denoted by past perfect. So the correct sequence of events is not coming out.
So we can eliminate this option.
So only option A is left.
The answer is option A.
