• A. a, b true c, d wrong
• B. d true a, b, c wrong
• C. c true a, b, d wrong
• D. b true a, c, d wrong
• E. a true b, c, d wrong

Answer 1

The correct option is A a, b true c, d wrong

As a young vascular plant grows, one or more strands of primary xylem form in its stems and roots. The first xylem to develop is called 'protoxylem'. Radial vascular bundles are typically found in the roots of monocots and dicots. Typical vascular bundles are conjoint vascular bundles.

So, the correct answer is 'a, b true c, d wrong.'
