💡 Detailed Explanation
Translation: Mr. Tanaka can play the guitar.
- Grammatical point: Expressing ability '〜ことができる' (can do ~).
- Explanation: The grammatical pattern for expressing potential or ability is '動詞辞書形 (Dictionary form) + ことが + できます/できる'. The verb for playing string instruments (like guitar, piano) is 弾く (ひく - hiku). Its dictionary form is 'ひく'.
- Why other choices are incorrect:
- ひきます (masu-form), ひいて (te-form), and ひかない (nai-form) cannot precede 'ことが できます'.
