Answer:
B) The sole criterion for Joanna's promotion was her effectiveness in meeting individual targets.
Step-by-step explanation:
Joanna wants to guide her sbordinates in executing various projects but they are not proactively coming to her for advise. This indicates that before her promotion she was very good at doing work individually and most likely did not work collectively to achieve results.
Based on this background tlshe was promoted on the basis of her individual efforts and her staff are not comfortable coming to her for guidance, since this was not her style before promotion.
Her approachable nature in building a team would not have been a criteria, if not it would have resulted in greater request for guidance from subordinates.
