A, C, and E are correct.

The formula for B, D, and F that you need is the formula for changes in equity, which is:
Ending Equity = Beginning Equity + Investments + Revenues - Expenses - Drawings

B. This can be rewritten as:
Investments = Ending Equity - Beginning Equity - Revenues + Expenses + Drawings

D. This can be rewritten as:
Drawings = Ending Equity - Beginning Equity - Investments - Revenues + Expenses

F. This can be rewritten as:
Revenues = Ending Equity - Beginning Equity - Investments + Expenses + Drawings
