It looks like the share price has hit the "Upper Circuit Limit", so trading is suspended for the day (or, possibly, there can be no sellers, only buyers).
The BSE page for Alok is currently (14:21 GMT, 26th June 2020) showing 18 notifications, the latest of which is "Touched Upper Circuit Rs. 48.20:
A circuit limit (upper or lower) is a limit beyond which a share's price is not allowed to move in a day, usually expressed as a percentage of the opening price. The limits are in place to stop large, volatile swings in a share's price.
Both Circuit Breaker on Investopedia and What is circuit breaker in stock market? from the Economic Times (of India) say that trading is suspended when a share's price hits either the upper or lower limit. If so, one might expect the Bid Price to be zero as well. However, Upper Circuit and Lower Circuit on
the GetPaidIndia website says:
When a stock hits an upper circuit, there will be only buyers and no sellers.
So, if someone wants to sell the stock, they can do so.
Similarly, when a stock hits a lower circuit, there will be only sellers and no buyers.
So, if someone wants to buy the stock, they can do so at the lower circuit.
If this last description is correct, then since the stock has hit the upper limit, there could be no buyers and so there is no offer price (shown as zero with zero quantity). However, if you're still allowed to sell, someone has to buy, so I'm not sure how applicable this is. (Perhaps selling to a marker-maker doesn't count?)
Either way, trading (or perhaps only buying) in Alok is suspended for the day (although the BSE would be closed now, anyway).
