{c}

Every <Euclidean distance> obeys the <triangle inequality>. The three recorded entries $d_{14}=0.67$, $d_{16}=2.88$ and $d_{46}=4.37$ violate it:
$$
\boxed{d_{46}=4.37>0.67+2.88=3.55=d_{41}+d_{16}.}
$$
\b[At least one of $0.67,\ 2.88,\ 4.37$ must be incorrect.] Two are in the final row as required. The gap is far larger than any possible rounding of entries to two decimal places.
