Answer:

option:B

Step-by-step explanation:

We are given the equation [tex]p-2(4-3p)=2p+7[/tex]

if we will get a unique value of p on solving the equation then it will have '1' solution.

so on solving for the above equation we have:

[tex]p-2\times4-2\times(-3p)=2p+7\\p-8+6p=2p+7\\7p-8=2p+7\\5p=15\\p=3[/tex]

Hence we get a unique value for 'p'.

so option B is correct.
