Answer 1

Answer: (B), (D)

The number of passengers boarding trains from $7:00\mathrm{AM}$ to $7:00\mathrm{PM}$ at a station

Explanation for the correct answer:

Histogram is a graphical representation of data if the data is represented using class-interval.

Example: Temperature recorded in different parts of the world. The data can be plotted as class-intervals of temperature in $x$-axis and number of cities whose temperature is in the interval in $y$-axis.

Option B and option C are correct because the data can be divided into class-intervals.

Hence histogram can be used for representing the data.

Therefore, options B and C are correct.
