Just wondering why the explanation in OG says that in answer choice D, as big as is an idiomatically incorrect expression of the comparison

Hi Junjun,

By itself, "as big as" is fine. But the verb phrase "to grow as big as..." here is incorrect.

We're not comparing anything; we're saying that the killer whale can grow to be 30 feet long. The idiom is "to grow to be..."

"...as" is used to compare two things. If we wanted to compare growth, we would write:

The killer whale can grow to be as big as a bus.

But we still need "to be."
