Answer:
none of the above
Step-by-step explanation:
Consider the following:
p(129) = 1·2·9 = 18
p(10·129) = p(1290) = 1·2·9·0 = 0 . . . . . statement I is not true
p(129+1) = p(130) = 1·3·0 = 0 . . . . . . . . . statement II is not true
p(2·129) = p(258) = 2·5·8 = 80 . . . . . . . statement III is not true
None of the offered statements must be true.
_____
