Alphabet test — formable word from letters of: RECOMMENDATION

Introduction / Context:
In this alphabet-test item, you must find the option that can be formed by using each letter from the source word at most once. The test checks attention to letter frequency (how many times a letter appears) and whether any required letter is missing altogether.

Given Data / Assumptions:

• Source word: RECOMMENDATION.
• Letters available (with counts): r(1), e(2), c(1), o(2), m(2), n(2), d(1), a(1), t(1), i(1).
• Rule: build a candidate only if every required letter exists in the pool with sufficient multiplicity.

Concept / Approach:
Construct a quick frequency map of the source word and then check each option by subtracting required letters. If any letter is missing or needed more times than available, that option is invalid.

Step-by-Step Solution:

Verification / Alternative check:
Recount letters after selection to ensure no count goes negative. MEDICO consumes at most one of each needed letter, all within limits.

Why Other Options Are Wrong:
They either require letters that do not occur in the source (e.g., U or S) or require a higher multiplicity (e.g., two R's or double C) than available.

Common Pitfalls:
Overlooking letter multiplicity (especially R, C) and assuming any semantically related word is acceptable. Meaning is irrelevant; feasibility is purely by letters and counts.

Final Answer:
MEDICO
