worry about / be worried about

Yes, but A's grammar was wrong.

but A's meaning is she worries about her children.A mean that she worries all the time.
B's meaning is she is worried about her children.b mean that she worries at that time.

An example:
I worry about my future. (all the time)
I am worried about my future. (at that time)

你的結論是對的Ａ句的worry作動詞用，而Ｂ句的worried則作形容詞用，

在牛津第六版，worried的條下也有以下的例句

I'm not worried about her --she can take care of herself.

在worry條下，也有一例
Don't worry about me. I'll be all right.

希望幫到你！

但當然你的A句，應用worries
