The correct answer is:
$\mathrm{V}_1 < \mathrm{V}_2 ; \mathrm{P}_1=\mathrm{P}_2$
In step up transformer the output voltage is greater than input voltage because the number of turns on the secondary is more than the number of turns in the primary. Therefore $\mathrm{V}_2>\mathrm{V}_1$
Input power is equal to output power.
$$
\therefore \mathrm{P}_1=\mathrm{P}_2
$$
Hence (4) is correct.
Input power is equal to output power.
$$
\therefore \mathrm{P}_1=\mathrm{P}_2
$$
Hence (4) is correct.
