@Julie-V,

Let's take a look at (A), (C), and (E).

(A) says, "Of all the peaks in the coastal mountain range, Mount
Williams is the tallest. Since the tallest peaks in the entire region
are in the coastal mountain range, Mount Williams must be the region’s
tallest peak."

(A) is actually a valid argument. The premise tells us that the
tallest peaks are in the coastal mountain range. This means that Mount
Williams is the tallest of the tallest peaks around, so it has to be
the region's tallest peak. Thus, (A) is out.

(C) says, "Susan Coleman is the oldest of the three children in her
family. Since the three Coleman children are each older than any of
the other children who live in their building, Susan Coleman must be
the oldest child now living in the building."

(C) is a valid argument. If the three Coleman children are older than
all of the other children in the building, then Susan Coleman must be
the oldest child in the building since she's the oldest Coleman child.
Thus, (C) is out.

(A) and (C) more or less follow the same logic, so you're correct about that.

For (E), yes, it's the best answer because "most beautiful" can be
viewed just as "most famous" is in the stimulus.

(E) says, "Of all the flowers grown in the university’s botanical
garden, the Oakland roses are the most beautiful. Since the
university’s botanical garden is the most beautiful garden in the
region, the Oakland roses grown in the garden must be the most
beautiful flowers grown in the entire region."

The argument is assuming that the most beautiful garden must also have
the most beautiful flowers. This is not necessarily true, and this
jump is the same type that the argument in the stimulus makes, so (E)
is the correct answer choice.

Does this make sense?
