Add the decimals.

$773.49 + $27.85 =

A

$791.34

B

$801.34

C

$790.34

D

$745.

To solve the problem, we simply add the two decimal numbers together:

\[
773.49 + 27.85
\]

Let's line up the numbers by their decimal points and add:

\[
\begin{array}{r}
  773.49 \\
+  27.85 \\
\hline
\end{array}
\]

Starting from the rightmost digit:

- **Hundredths place**: $ 9 + 5 = 14 $. Write down 4 and carry over 1.
- **Tenths place**: $ 4 + 8 = 12 $ (plus the carried over 1, gives us 13). Write down 3 and carry over 1.
- **Units place**: $ 3 + 7 = 10 $ (plus the carried over 1, gives us 11). Write down 1 and carry over 1.
- **Tens place**: $ 7 + 2 = 9 $ (plus the carried over 1, gives us 10). Write down 0 and carry over 1.
- **Hundreds place**: $ 7 $ (plus the carried over 1, gives us 8).

Adding all these together, we get:

\[
801.34
\]

Therefore, the correct answer is:

**B. $801.34**
