The correct answer B. It is an end rhyme since the two words at the end of each line rhyme, namely the words 'place' and 'face'. In order to distiguish a rhyme, you need to look at two words with the same or similar sounds. The rhyming words in this poem have the same sound, and since they are placed at the end of the line, they are a clear example of end rhyme. Internal rhymes are also common in Dickinson's poems, but in these lines the rhyme between two words does not really stand out.
