$\underline{\textbf{Answer:}\Rightarrow}\;\text{Option}\;\textbf{1)a-iv,b-iii,c-ii,d-i}$
$\underline{\textbf{Explanation:}\Rightarrow}$
$\underline{\textbf{a)Micro-operation:}\Rightarrow}$
It is the basic operations that are performed on the stored data in registers, such as performing Arithmetic and Logic operations and transferring data between two registers.
$\therefore$ $\mathbf{(iv)}$ matches.

$\underline{\textbf{b)Micro programmed control Unit:}\Rightarrow}$
The binary control variables of this control unit are stored in memory.
It deals with several units of software but at the micro-level, such as micro-operation, micro-program, and micro-instructions.
$\therefore$ It is related to the control memory.
$\therefore$ $\mathbf{(iii)}$ matches.
$\textbf{Hardwired Control Unit:}$
The generation of control signals by hardware using traditional logic architectures.

$\underline{\textbf{c) Interrupts:}\Rightarrow}$
It is an input signal that is given to the processor which implies that a certain event requires immediate consideration.
It is usually done to execute computer multitasking, mainly in real-time computing.
It is just temporary.
Systems that make use of interrupts this way are called to be $\textbf{interrupt-driven}$.
$\therefore$ $\mathbf{(ii)}$ matches.
https://en.wikipedia.org/wiki/Interrupt
$\underline{\textbf{c) Micro-instruction:}\Rightarrow}$
Control words in the micro routine are called micro-instructions.
Each microinstruction is categorized into $5$ fields: label, micro-operations, CD, BR, and AD.
$\therefore$ $\mathbf{(i)}$ matches.
$\therefore \;1)$ is the right option.
