Answer 1

The correct option is B The bars are marked with gap.

The given historgram is

The first option is "The axes are not labeled": This error is not there, since the historgram is labeled.

The next option is "The bars are marked with gap": It is an error, since the bars are marked with a gap.

The next option is "The frequencies are wrongly marked": This error is not there, since the frequencies that are marked are correct.

The last option is "No error": This is false, since there is an error in the graph.

We observe that, there is a gap in between the bars.
