Answer :
We begin by examining the numerical part of the series. The numbers in the series are:
$$10,\; 21,\; 32,\; 43,\; 54,\; 65.$$
Notice that each term increases by 11:
$$21 - 10 = 11, \quad 32 - 21 = 11, \quad \text{and so on.}$$
Thus, the next number is calculated as:
$$65 + 11 = 76.$$
Next, let’s analyze the letter sequence:
$$A,\; b,\; C,\; d,\; E,\; f.$$
A pattern is evident where the letters alternate in case:
- The 1st, 3rd, and 5th letters are uppercase.
- The 2nd, 4th, and 6th letters are lowercase.
This indicates that the 7th letter should be in uppercase. In the alphabet, the 7th letter is:
$$A, \; B, \; C, \; D, \; E, \; F, \; G.$$
Thus, the letter for the 7th term is $G$.
Finally, combining the next number and the letter, the next term in the series is:
$$76G.$$
Among the given options, the correct answer is **76 G**.
$$10,\; 21,\; 32,\; 43,\; 54,\; 65.$$
