The correct answer is: Infection thread carries the bacteria to xylem and phloem.
During root nodule formation infection thread carries the bacteria into the cortex of the root, where they initiates the nodule formation in the cortex of the root. Then the bacteria are released from the thread into the cortical cells which leads to differentiation of specialized nitrogen fixing cells. The nodule establishes a direct vascular connection with the host for exchange of nutrients.
