Concerns about public health led to the construction between 1876 and 1904 of three separate sewer systems to serve metropolitan Boston.

A. Concerns about public health led to the construction between 1876 and 1904 of three separate sewer systems to serve
B. Concerns about public health have led to the construction of three separate sewer systems between 1876 and 1904 to serve

D. There were concerns about public health leading to the construction between 1876 and 1904 of three separate sewer systems serving

IMO-B : The modifier “Led to the construction” has to be close to “three separate sewer system”.

The construction of the sewer system has already been done. It is past tense. We can't have "have led to the construction" here.

IMO A

Dude!

In choice B: 'between 1876 and 1904 ' is modifying systems not the construction..what do you say?
