Rearrange the parts of the sentence in the correct order.
The revolutionary CRISPR-Cas9 technique,
P. raising concerns about ethical implications
Q. in human germline editing and ecological interventions
R. has transformed the landscape of biotechnology,
S. enabling precise modifications at the genetic level,

Correct option is D

Option (d) is the correct order of the given sentences.
• The finite predicate that completes the subject “The revolutionary CRISPR-Cas9 technique,” is in R: “has transformed the landscape of biotechnology,” so R must come first.
• A participial, result-nuance modifier follows naturally: S “enabling precise modifications at the genetic level,” adds how/with what capability the transformation occurs.
• Another participial of consequence/repercussion is P “raising concerns about ethical implications,” which logically follows the capability mentioned in S.
• The prepositional phrase Q “in human germline editing and ecological interventions” specifies the domain of those ethical concerns and therefore directly completes P.
• Hence the sequence is R–S–P–Q.
