Hi, this looks like a Red-back Spider (Latrodectus hasselti). Somewhat tentatively though because Latrodectus erythromelas is another I see listed for India and I don’t know what that looks like. It may or may not be similar…

I found a possible image of L. erythromelas. It is described as being smaller than L. hasselti with a wider and relatively shorter red stripe on the abdomen and lacking the hourglass on the ventral edit: which may only be the case on preserved specimens (still reading up on these). https://threatenedtaxa.org/index.php/JoTT/article/download/2380/3428/6213

I am thinking your spider might be L. erythromelas based on the shape of the red stripe compared to the examples I see of the two species.
