Find the coordinates of the foci, the vertices, the length of the major axis, the minor axis, the eccentricity and the length of the latus rectum of the ellipse $16x^2+y^2=16$

Question

$\begin{array}{1 1}Eccentricity =\frac{\sqrt 15}{4}\quad Latus\; Rectum = \frac{1}{2} \\ Eccentricity =\frac{\sqrt 15}{2}\quad Latus \;Rectum = \frac{1}{2} \\Eccentricity =\frac{\sqrt 15}{4}\quad Latus \;Rectum = \frac{1}{4} \\ Eccentricity =\frac{\sqrt 15}{2}\quad Latus \;Rectum = \frac{1}{4} \end{array}$
