To answer this question, you need to have knowledge about the 8085 microprocessor and its package type.
The 8085 microprocessor is commonly available in a 40-pin DIP (Dual In-line Package) format. This means that it has 40 pins arranged in two parallel rows.
Option A) 40 - This option is correct because the 8085 microprocessor is based on a 40-pin DIP package.
Option B) 16 - This option is incorrect because the 8085 microprocessor is not based on a 16-pin DIP package.
Option C) 60 - This option is incorrect because the 8085 microprocessor is not based on a 60-pin DIP package.
Option D) 45 - This option is incorrect because the 8085 microprocessor is not based on a 45-pin DIP package.
The correct answer is option A) 40. This option is correct because the 8085 microprocessor is based on a 40-pin DIP package.
