A.Although at one time children’s programming had been limited to a few hours a week, now, however, there are at least four cable
networks that dedicate themselves
--Wrong because of the usage of Although and However.
Will it be correct if we remove the unnecessary however?
no.
the sentence describes a point observation made "at one time" -- i.e., at a specific time in the past -- so the past perfect is incorrect.
B.With children’s programming having been limited at one time to a few hours a week, now at least four cable networks have dedicated themselves
--Having been is incorrect incorrect here...
Will it be correct if it is written as :
With children's programming been limited at one time to a few hours a week, there are now at least..
definitely not. in fact, "with + NOUN + been..." would be incorrect under any circumstances.
C. Once limited to a few hours a week, there are now at least four cable networks with children’s programming that dedicate themselves
--I believe that the wording children's programming is redundant here. If we write it as :
Once limited to a few hours a week, children's programming now constitute....
that change would make the modifier work, but the resulting construction would be incompatible with the non-underlined part of the sentence.
there is also a subject-verb error in your new version: "programming" doesn't agree with "constitute".
E. While children’s programming had once been limited to a few hours a week, at least four cable networks are now dedicated
If we write the above as :
While children's programming had once been limited to a few hours a week, there are now at least..
same problem as in (a).
