D1, 2, 3, 4 & 5

Correct answer: (B) 1, 2 & 4 only

Explanation

Arithmetic mean, median and mode are the measures of central tendency here.

The arithmetic mean is the balancing average of all values.

The median is the middle value dividing an ordered series into two halves.

The mode is the most frequently occurring value in the data.

Range is a measure of dispersion, not of central tendency, so it is excluded.

The second decile is a positional partition value, again not a central-tendency measure.
