It’s D. He goes into details about how the events that took place will be remembered. All the difference and acts of injustice. I hope that helped.

The last option: If it hadn't been for Rosa's warning, we would have been caught in the sudden, torrential rainstorm during Saturday's picnic.

You need an apostrophe in hadn't because it combines had not into a contraction. Rosa's and Saturday's both need an apostrophe to show ownership. Rosa owns the warning, and Saturday owns the picnic. The comma after warning is needed because it separates the dependent clause with the independent clause. The comma between sudden and torrential separates the list of adjectives. Without the comma sudden would be describing torrential rather than rainstorm.
