If it is not the S1C D, what is the S1C with one real engine at the
corner fired on MTF ?

The caption of that picture says that the thing on the corner that
*looks* like an F-1 engine is a dummy...

The photograph shows the 300,000 pound S-IC stage being lifted
from its transporter into place inside the 360-foot tall test
stand. This dynamic test booster has one dummy F-1 engine and
weight simulators are used at the other four engine positions.
