Explanation:

In 8085 microprocessor, there are five types of interrupts namely TRAP, RST 7.5, RST 6.5, RST 5.5, and INTR. Among these, TRAP is a non-maskable interrupt while the rest are maskable interrupts. RST 7.5, RST 6.5, and RST 5.5 are vectored interrupts while INTR is a non-vectored interrupt.

What is a Vectored Interrupt?

A vectored interrupt is an interrupt in which the interrupting device informs the processor of the specific address or vector where the interrupt service routine (ISR) is located. In other words, the interrupting device provides the address of the ISR to the processor. This allows the processor to directly jump to the ISR without having to search for it.

RST 5.5, RST 6.5, and RST 7.5

RST 5.5, RST 6.5, and RST 7.5 are vectored interrupts in 8085 microprocessor. The vector address for RST 5.5 is 0024H, the vector address for RST 6.5 is 0034H, and the vector address for RST 7.5 is 0044H.

INTR Interrupt

INTR is a non-vectored interrupt in 8085 microprocessor. This means that the interrupting device does not provide the address of the ISR to the processor. Instead, the processor has to search for the ISR in a fixed location in memory. The fixed location for the INTR ISR is 003CH.

Conclusion

In conclusion, the correct answer is option 'D' because INTR is a non-vectored interrupt in 8085 microprocessor. RST 5.5, RST 6.5, and RST 7.5 are vectored interrupts in 8085 microprocessor.
