{'achievement': [0, 0, 4, 1], 'scientists': [2, 2, 8, 11]}

The correct answer is Option 1 as it correctly matches the scientists with their respective achievements.

A. Arber and Smith are known for discovering endonucleases, enzymes that cleave the phosphodiester bond within a polynucleotide chain, hence matching with "2".

B. Feldman is associated with developing transgenic plants with Agrobacterium T-DNA, thus matching with "1". Transgenic plants are modified to enhance desired traits like improved nutritional content or resistance to pests.

C. Mullis discovered the polymerase chain reaction (PCR), indicated by "4". PCR is a method widely used to quickly make millions to billions of copies of a specific DNA sample.

D. Temin and Baltimore made the discovery of reverse transcriptase, coded as "3". Reverse transcriptase is an enzyme that catalyzes the formation of DNA from an RNA template in reverse transcription.

Each of the other options has at least one incorrect match between the scientist and their achievement, making them incorrect.
