In Hexa it is okay as (2B) but in Binary it will be (00101011).

If you go for direct conversion of 2 it will be 0010 & B will be 1011 so totally it would be 00101011.

00101011 = 2B(H)?

For hexadecimal.

0010 = 2.
1011 = B.

One simple logic among answers is 43 is odd number. So always LSB is 1 and Hexadecimal also odd number should come as left nibble like (B).

For hexadecimal to binary conversion of (43) which is in decimal form, convert 4 and the 3 into 4 bits separately, and then combine the answer.

4 = 0100.
3 = 0011.
43 = 01000011.

Hex to decimal:

Divide 43 by 2 as shown:

43/2 = 21 rem 1 again divide 21 with 2.

21/2 = 10 rem 1.
10/2 = 5 rem 0.
5/2 = 2 rem 1.
2/2 = 1 rem 0.

00101011 = 2B.
