Correct Answer - Option 2 : 55000

**Bit Rate:**

Bit Rate is the number of Bits that are converged or processed per unit. It is denoted by R_{b}.

Baud Rate: It is defined as no. of signal or samples processed per unit time.

\(Bit\;Rate = \frac{{Baud\;Rate}}{{No.\;of\;bits}}\)

**NOTE:**

If there is M symbols/sample then no. of Bits (n) = log^{2} M

**Solution:**

Since 500 Bits of data processed by UART in 100 ms. Then

\(Bit\;Rate\;\left( {{R_b}} \right) = \frac{{500}}{{100 \times {{10}^{ - 3}}}} = 5\;kbps\) ∵ 1000 Bit Bit = 1 KB

Start bit = 1 Stop bit = 2 Data bit = 8

Total no. of Bits = 8 + 2 + 1 = 11

Baud Rate = No. of bits × R_{b} = 11 × 5 = 55 KBPS = 55000 BPS
