ANSWER:  b. 2/p  +  3/(p+1) = 5

SOLUTION:
LCD: (p) (p+1)
Multiply each term by LCD, then simplify:

(p)(p+1) [ \frac{2}{p} + \frac{3}{p+1} =5 ]

2p + 2 + 3p = (5p) (p+1)
2p + 3p + 2 = 5p² + 5p
5p² + 5p - 5p + 2 = 0
5p² + 2 = 0 ⇒  the equation is a second degree polynomial

Note:  The rest of the given items are linear equation, a firs-degree equation.
