Adım Adım Çözüm

1
Identify the clause following the subject 'Wegener' to determine if it is essential or nonessential.
The clause 'who was initially dismissed by his peers' provides descriptive, nonessential details about Wegener that are not required to identify him.
Nonessential information must be set off from the rest of the sentence with matching punctuation marks.
2
Evaluate the options for correct and symmetrical punctuation.
The option with matching em dashes correctly isolates the nonessential clause, whereas the other options either mix punctuation marks or omit them entirely.
Standard English conventions require nonessential elements to be enclosed by a pair of matching commas, dashes, or parentheses.
