Final answer:
After performing scansion on the provided excerpts from Wordsworth's poem, it is determined that Option b and Option d are the lines written in iambic tetrameter.
Step-by-step explanation:
To determine which lines from the excerpt of "Ode: Intimations of Immortality from Recollections of Early Childhood" by William Wordsworth are written in iambic tetrameter, we need to recognize that this means the lines would have four sets of iambs (an unstressed syllable followed by a stressed syllable). We perform scansion to measure the meter of the lines.
After analyzing the options, we find that:
• Option a ("There was a time when meadow, grove, and stream") is written in iambic pentameter.
• Option b ("The earth, and every common sight to me did seem") is indeed in iambic tetrameter.
• Option c ("Apparell'd in celestial light") is incomplete and doesn't fit any regular meter on its own.
• Option d ("It is not now as it hath been yore:") is also in iambic tetrameter.
• Option e ("The things which I have seen now I can see more") is in iambic pentameter with an extra beat.
The correct options that are written in iambic tetrameter are Option b and Option d.
