Upon heating, compound X is converted to Y, which has the same molecular formula as that of X. The ${ }^{1} \mathrm{H}$ NMR spectrum of Y shows two doublets centered at 3.0 ppm (separation of two lines ~ 20 Hz) and 4.0 ppm (separation of two ~ 15 Hz) respectively. Compound Y is:

(a)$\left(\mathrm{CH}_{3} \mathrm{O}\right)_{2} \mathrm{P}(\mathrm{O})(\mathrm{OH})$

(b)$\left(\mathrm{CH}_{3} \mathrm{O}\right)_{3} \mathrm{P}(\mathrm{O})$

(c)$\left(\mathrm{CH}_{3} \mathrm{O}\right)_{2}\left(\mathrm{CH}_{3}\right) \mathrm{P}(\mathrm{O})$

(d)$\left(\mathrm{CH}_{3} \mathrm{O}\right)_{2}\left(\mathrm{CH}_{3}\right) \mathrm{P}(\mathrm{OH})$
