HUF taxation and deductions

under HUF PAN, should all investments be made separately to claim deductions under chapter VI A - like 80C, 80D etc..

or karta's investments can be claimed in HUF as well

karta's income is exceeding BEL and he is filing his ITR claiming all the deductions under his PAN as well

so pls guide us on this
for HUF should we make separate investments ?
