我理解的怕不对，专门帮你找了大神ron的解释，窃喜这次俺理解对了

From time X on(ward)" is a perfectly respectable construction. It means, essentially, "starting at time X".

The problem with D is that comma + __ing refers to the subject + action of the preceding sentence. So, choices D and E imply that the "widely known images" photographed the park, rather than that Adams did. Doesn't make sense.

why B and C are wrong?, pls explain.

I see "starting" in B and C is wrong because there is not comma for "starting" to refer to the subject of the previous clause and there is no legitimate noun preceding immediately for the "staring" to refer to

but I still want a full explanation of B and D. I feel uneasy with B and C.

B and C are redundant. (C is double- or even triple-redundant!)

If you have the notions of "continuously" and "from his teenage years", then there's no need for "starting from...", which is already implied.
