(a) and (c)

step-by-step explanation:

in δabc, ab=1, ac=bc=2 and δdef, de=3, df=7 and ef=6

now, (a)

hence the given triangles are not similar.

(b)

=

hence,the triangles are similar.

(c)

hence, the triangles are not similar.

(d)

=

hence, triangles are similar.

hence, option a and c shows that triangles are not similar.
