Answer:


(-11,0) and
(11,0).

Explanation:

The given ellipse has the equation:


(x^2)/(121)+(y^2)/(1)=1

This can be rewritten as


(x^2)/(11^2)+(y^2)/(1^2)=1

We compare this to the general equation of the ellipse:


(x^2)/(a^2)+(y^2)/(b^2)=1

We have
a=11 and
b=1

The vertices of this ellipse are at
(-a,0) and
(+a,0).

Therefore the vertices of this ellipse are at
(-11,0) and
(11,0).

The correct choice is A.
