Following iteration is the pattern,
$$28:36\longrightarrow\ \ 4\times\ 7\ :\ 4\times\ 9$$
$$63:72\longrightarrow\ \ 9\times\ 7\ :\ 9\times\ 8$$
$$119:153\longrightarrow\ \ 17\times\ 7\ :\ 17\times\ 9$$
$$91:117\longrightarrow\ \ 13\times\ 7\ :\ 13\times\ 9$$
$$133:171\longrightarrow\ \ 19\times\ 7\ :\ 19\times\ 9$$
So, Option A is different from others.
