The sides PQ and PR of $$\triangle$$ PQR are produced to points S and T, respectively. The bisectors of $$\angle$$ SQR and $$\angle$$ TRQ meet at point U. If $$\angle QUR = 69^{\circ}$$, then the measure of $$\angle$$ P is:

A

$$21^{\circ}$$

B

$$31^{\circ}$$

C

$$69^{\circ}$$

D

$$42^{\circ}$$
