Average values of the re-aeration rate constant for river $\mathrm{X}$ and river $\mathrm{Y}$ are $0.92$ per day and $1.12$ per day, respectively. Average de-oxygenation rate constants for the same rivers are $0.23$ per day and $0.35$ per day respectively. Then, which of the following statement(s) is/are correct?
- Self-purification capacity of river $\mathrm{Y}$ is more than that of river $\mathrm{X}$.
- Self-purification capacity of river $\mathrm{X}$ is more than that of river $\mathrm{Y}$.
- River Y has higher turbulence and/or higher velocity and/or higher algal growth compared to river $\mathrm{X}$.
- Pollutants in river $\mathrm{X}$ are more biodegradable than that in river $\mathrm{Y}$.
