(A) In the given $P-V$ diagram:$1$. $AB$ is an isobaric process (constant pressure, $P = 	ext{constant}$).$2$. $BC$ is an isothermal process (constant temperature, $T = 	ext{constant}$), as it follows the curve $PV = 	ext{constant}$.$3$. $CD$ is an isochoric process (constant volume, $V = 	ext{constant}$).$4$. $DA$ is an isothermal process (constant temperature, $T = 	ext{constant}$).Now, let's analyze these in a $P-T$ diagram:$1$. For $AB$ $(P = 	ext{constant})$: In a $P-T$ diagram, this is a vertical line.$2$. For $BC$ $(T = 	ext{constant})$: In a $P-T$ diagram, this is a horizontal line.$3$. For $CD$ $(V = 	ext{constant})$: Since $P/T = nR/V$, $P \propto T$. This is a straight line passing through the origin.$4$. For $DA$ $(T = 	ext{constant})$: In a $P-T$ diagram, this is a horizontal line.Comparing this with the given options, the diagram that matches these characteristics is the one where $AB$ is vertical, $BC$ is horizontal, $CD$ is a line through the origin, and $DA$ is horizontal. This corresponds to the first option.

$A$ cyclic process $ABCD$ is shown in the given $P-V$ diagram. In the following answer, the one that represents the same process as in the $P-T$ diagram is:
