The correct answer is C. 40 pin with DIP.
A DIP (dual in-line package) is a type of integrated circuit package that has two rows of pins that are parallel to each other. The 8051 microcontroller is available in a 40-pin DIP package.
A QFP (quad flat package) is a type of integrated circuit package that has a square or rectangular shape with pins that are arranged on all four sides. The 8051 microcontroller is not available in a 60-pin QFP package.
An LQFP (low-profile quad flat package) is a type of integrated circuit package that is similar to a QFP, but it has a lower profile. The 8051 microcontroller is not available in a 60-pin LQFP package.
A PLCC (plastic leaded chip carrier) is a type of integrated circuit package that has a rectangular shape with pins that are arranged on all four sides. The 8051 microcontroller is not available in a 60-pin PLCC package.
A SOIC (small outline integrated circuit) is a type of integrated circuit package that has a small, rectangular shape with pins that are arranged in a single row. The 8051 microcontroller is not available in a 60-pin SOIC package.
