$A. \\ 16-(4+7)=12+7=19 - \hbox{wrong, parentheses first:} \\ 16-(4+7)=16-11=5 \\ \\
B. \\
10+(6 \div 3)=10+2=12 - \hbox{correct} \\ \\
C. \\
7 \times 6+4=7 \times 10=70 - \hbox{wrong, multiplication first:} \\
7 \times 6+4=42+4=46 \\ \\
D. \\
2+5 \times 7=2+35=37 - \hbox{correct}
$

Statements B and D are true.
