Consider triangles ABC and A1B1C1.
It is known that they are similar and the aspect ratio AB / A1B1 = B1C1 / BC = 1/2.
Then the only option in which the similarity of triangles will be preserved, and the indicated proportionality of the sides will be as follows:
<A = <C1, <B = <B1, <C = <A1, and therefore
AB is proportional to B1C1,
BC is proportional to A1B1,
AC is proportional to A1C1.
