This question is not taken from any source, but very much similar to a question of a good source. It is for my understanding and doubt clearance...
To David, Picasso was his favorite long before it was respectable to be a connoisseur of art, and David remained an art lover during xxxxxxxxxx
A. To David, Picasso was his favorite long before it was respectable to be a connoisseur of art,
B. For David, long before it was respectable to be a connoisseur of art, Picasso was his favorite,
C. David made Picasso his favorite long before to be a connoisseur of art was respectable,
D. Long before it was respectable to be a connoisseur of art, David made Picasso his favorite,
E. Long before it was respectable being a connoisseur of art, Picasso was favorite to David,
The very much similar and identical problem of a good source has D as OA.
My humble questions are: Can we eliminate A, B & E solely because of the violation of parallelism?
What is wrong in C? If we write rephrase C as "David made Picasso his favorite long before it was respectable to be a connoisseur of art,", will it be right?
Is the use of 'being' in E is awkward/unnecessary?
Between 'To David' and 'For David' (as in A & B), which one is better choice?
