The growth and development of multicellular organisms rely on mitosis and cell expansion. Researchers tracking the development of male laboratory mice (C57BL/6 C57BL/6\,C57BL/6 strain) plotted a body mass percentile chart across their early growth phases.

At 6 weeks of age, a male mouse is weighed and found to have a body mass of 19.5 g.
Which of the following is the percentile range for the body mass of this mouse?
10th to 25th percentile
25th to 50th percentile
50th to 75th percentile
75th to 90th percentile
