a.

c.

b.
Updike
d.
Lewis

The answer is John Updike

Explanation: During and after the uprising of  the 1920s people were reeling under the prohibitions and other side effects. It impacted the way they thought especially the intellectuals. it kind of left an indelible mark in their thinking and reflected in the way they wrote.

Several prominent writers of that era such Fitzgerald, Hemingway, Lewis, Wharton, Passos needled to express what they felt, the despair and hopelessness that brought in the pathos and gravity of what it was like in those times.

But John Updike was a non-conformist, it wouldn't like to be slotted in a box. He was born with certain passion to express issues that he felt deeply about which sometimes were on the 'wrong' side. Yet there was some amount of liberal consensus.

He reflected on subjects that didn't have general consensus. He couldn't have expressed the disillusionment, malaise and turmoil of the authors of 1920's because he was born in 1932, a decade later and we he began writing, effects of the uprising were weaning off.
