Select the odd one out from the given options: (A) LNM (B) RNK (C) JKV (D) HLW

• (A) LNM: L=12, N=14, M=13
• (B) RNK: R=18, N=14, K=11
• (C) JKV: J=10, K=11, V=22
• (D) HLW: H=8, L=12, W=23

• (A) Sum for LNM: $12 + 14 + 13 = 39$
• (B) Sum for RNK: $18 + 14 + 11 = 43$
• (C) Sum for JKV: $10 + 11 + 22 = 43$
• (D) Sum for HLW: $8 + 12 + 23 = 43$

The sums for options (B), (C), and (D) are all 43, while the sum for option (A) is 39. Therefore, LNM is the odd one out.

The final answer is $\boxed{\text{A}}$

• (A) • : This is a bullet point or dot, commonly used as a punctuation mark or for lists.
• (B) ; : This is a semicolon, which is a punctuation mark.
• (C) " : This is a double quotation mark, which is a punctuation mark.
• (D) + : This is a plus sign, which is a mathematical operator.

Options (A), (B), and (C) are all types of punctuation marks or text symbols. Option (D) is a mathematical operator. Thus, the plus sign is the odd one out.

The final answer is $\boxed{\text{D}}$
