The interval in which \( x \) must lie so that the numerically greatest term in the expansion of
\( \mathrm{P} \)
\( (1-x)^{21} \) has the numerically greatest coefficient is
(1) \( \left[\frac{5}{6}, \frac{6}{5}\right] \)
(2) \( \left(\frac{5}{6}, \frac{6}{5}\right) \)
(3) \( \left(\frac{4}{5}, \frac{5}{4}\right) \)
(4) \( \left[\frac{4}{5}, \frac{5}{4}\right] \)
