EAD application: Need correct eligible category for L2 Extension

[sujith3]

Hello, my L1B visa is going to get expired in next month. So applied for L1B extension along with my wife's L2 extension. We have received the receipt for our I-129 and I-539 application. Now I would like to renew my wife's EAD, but in I-765 application, I am confused of correct eligibility category for this case. Can any one help me in identifying the correct category in this scenario.

Thanks

Same category as she currently has, (a)(18)
