The slope field shown below corresponds to which differential equation?
(a) d y d t = y ( y + 1 ) {\displaystyle {\frac {dy}{dt}}=y(y+1)}
(b) d y d t = ( y − 1 ) ( y + 1 ) {\displaystyle {\frac {dy}{dt}}=(y-1)(y+1)}
(c) d y d t = − ( y − 1 ) ( y + 1 ) {\displaystyle {\frac {dy}{dt}}=-(y-1)(y+1)}
(d) d y d t = y ( y − 1 ) {\displaystyle {\frac {dy}{dt}}=y(y-1)}
(e) d y d t = − y ( y + 1 ) {\displaystyle {\frac {dy}{dt}}=-y(y+1)}
