Short term Capital Gain Taxability under new regime if total income is 8 Lacs

Hi Friends,

I was going through multiple blogs, but not clear on below points. Could you please help me to understand of correct tax treatment

A) My wife have earned Short term capital Gain of 6 Lacs from Treasury bills investment. Is she also exempted as per new regime Rebate limit (Max of 7 Lacs) ?

B) My mom earned Dividend of 5.3 Lacs from Liquid bees and earned  Short term capital Gain of 1.3 Lacs from Treasury bills. Is she also exempted as per new regime Rebate limit (Max of 7 Lacs) ?

Could you please advise us ?

Thanks & Regards,
